Nitrogen & Phosphorus Cycles: Always Recycle! Part 2 - Crash Course Ecology #9

[@tinkbday]

Honestly, I've almost always had science teachers that don't really explain/teach the material. They usually just tell us what we're supposed to be learning, give us a busy-work activity, and expect us to learn the material at home in time for the next test. Finally, about a quarter of the way into my freshman bio class, I discovered Hank's videos and they've been a total life-saver! Thanks to these videos I have excelled in my science courses despite having lazy teachers and am much better prepared for a future career in science. Thank you for making me love science!

[@ahlaeyajudon4662]

I totally agree !

[@hollieshelton5358]

Mrs. Barr

[@Orf]

Lazy teachers suck

[@abyssal666nocturnus]

My only complaint with this video is that there is no image of the cycle. it really helps to see the cycles. viewers could pause and examine them too.

[@christopherrogers8220]

look up one yourself...

[@abyssal666nocturnus]

i know you could, and i have but i mean, how hard is it to include...they have a graphic animation team....

[@moimoi819]

Abyssal Nocturnus but how hard is it to look one up...?

[@abyssal666nocturnus]

if you were explaining the ABC's to a child would you show things that started with "A" "B" and "C" but never show the characters of the ABC's?.....I mean im not like mad or anything im just pointing it out..

[@moimoi819]

Sure. that's understandable. but as an adult, if you know that you need visuals to help you understand, is it so hard to search them out rather than have it handed to you like a child would require??

[@Ghostdrone25]

I wish hank was my science teacher.

[@adityahegde4560]

You bet!

[@gisaiah43v7]

[@thatwavyblackguy]

thumbs up if you have a test/exam tomorrow

[@turtlemaster2291]

today m8

[@Armyguywizerdo16]

I will soon have a test on this, but i am trying to understand this right now, because my teacher does not know how to teach at all

[@alyahmed4731]

Armyguywizerdo16 i know ur feel bro :'), RESPECT for brothers struggling at school cuz of bad teachers.

[@nandhinigunasekaran6833]

I do!!!!

[@alexandramcosker2730]

***** AP environmental Science Exam (uh oh gonna faaaail...)

[@cloverring]

GOOD LUCK GUYS ON YOUR EXAMS TOMORROW MORNING! Remember to eat a balanced breakfast!

[@piratenoise1238]

Lmao how did you know 😭😂😂

[@ashasalelkar1248]

Amina Russ that's why u are here :p

[@awesomelytoxic8912]

Thank you❤️❤️

[@ChillExpressions]

Lol wat is dis

[@bradenbowker9420]

How about two Reeses Cups and a Redbull

[@AdannaMadueke]

Bless you for making these videos. This is what I call a life saving channel...

[@mxtomituck]

This video did a better job of explaining this concept than the class I'm actually paying for.

[@zaralee652]

thanks a lot (: I often prefer watching your videos than reading the textbook because you do a better job at explaining

[@TheElectrozoid]

*Nitrogen.* (waves around arms crazily)

[@sleepyfionna2188]

Same

[@lykkelundgrensassner1248]

i truly wonder how many grades and students this channel have saved. Im kinda "thank you for my degree as a Biologist".

[@prettydopesailing]

Love Hank's work so much! speed 0.5 = intoxicated Hank. have fun!

[@elizamunday6933]

Ugh the nitrogen cycle is so complicated! Couldn't never have understood it if it hadn't been for Crash Course. Absolute lifesaver

[@lilybetgates9332]

literally just watched his insta "official remission" video and opened this I think I might cry I loved CC so much growing up and love him as a creator so much now

[@MadelineOng]

bless this channel

[@Samoa102]

This video is helping me for my AP Bio presentation, where I need to present all four cycles and teach my whole class about it. Right when I started the video it kept stopping and reloading during the part he was saying, "There's nothing quite so terrible as needing something right in front of you, but not being able to get it." Coincidence at its finest. Anyways, thank you very much Hank, you really helped my understanding!

[@AngelKivia]

You said more than my textbook has written.

[@betabotreborn3755]

bill nye of 21st century

[@ciceroaraujo5183]

Correct

[@xochitllee24]

+BetaBotReborn Agreed.

[@kalojiostuff]

HANK HANK HANK *hank green the science fiend*

[@samhaley69]

yes

[@shilpashivadasan5115]

BetaBotReborn why does hank always sound so sarcastic tho? like "herbivores eat plants" *smirks*

[@elijahgardner3060]

I was procrastinating by watching mental floss, and dreading learning about the nitrogen cycle. I was pleasantly surprised with how interesting and helpful you were. How wonderfully ironic that it's two brothers that are the devil and angel on my shoulder.

[@alliecat5358]

I have finals tomorrow. You saved me. Thank you. I love you.

[@FairyofWhatever]

I love how excited he seems about everything! It really helps me to stay focused on what's being said. The best guy I found for Economics on KZbin literally puts me to sleep. Hank's a life saver, thanks!

[@daisydee2977]

Huge thank you to everyone involved in this! Amber, Peter, Michael, Nick, Jesslyn, Hank, Blake, and Brandon, youève all done a wonderful job making this entertaining and informative!

[@brionyderbyshire3391]

I'm currently doing A level biology and I struggle with a couple of learning difficulties so I usually have to constantly learn something over and over until it sticks but with your videos you make it so clear to understand how science works, you've helped me a lot over the year so thank you! I'll probably need you when I go uni too!

[@davidcamposbrandao2215]

Hank I have an exam tomorrow on this. Thank you again for this past 5 years. Saving the day

[@ryzaharukawa5714]

When 5 minutes on crash course gives you a clearer understanding of the nitrogen cycle than an hour of bio lesson at school Thanks for saving a life, crash course

[@isabelsamayoa7961]

GOD BLESS YOUR SOUL, HANK GREEN

[@williusethis]

I had a 200 term word to definition matching assignment for my environmental science class over break. One of the definitions was "a cycle with no atmospheric component" and I was completely stumped. God bless crash course.

[@loveh6094]

You guys are life-savers, seriously Bio is not an easy subject for me and you guys make it actually understandable! Thank you lots, the A's that I have gotten are because of you guys.

[@vesabarileva9001]

This is so entertaining and educating. It's way more fun than science class at school and here I actually learn so much in one video that just as a comparison, at school it would be a month worth of boring classes from textbook. Thanks!! :)

[@inogeni]

You're on KZbin, never alone! :D Happy New Year!

[@alligrim]

Your videos have always been awesome, but now they're also getting me an A in Honors Biology! Thanks, Hank! :)

[@zgeks5gd7]

thanks Hank, once again you've saved my project (and also aided my procrastination level xD) your videos are so concise, and yet mange to effectively condense a month of teachings into a few minutes.

[@therealablert]

Never thought I would use crash course in sophomore year of college

[@SweetSky__]

I started cracking up by of the way he said - "we make our own amino acids, then we can pee.. or poop it out... or... die" I love his straight-faced sense of humor

[@aspenlovesbirds]

Absolutely awesome! Seriously, you make science so much easier than any of the people that have ever taught to my class in person. Not to mention, the colorful graphics and humor lighten the mood. Thanks for saving my grade. :)

[@jocarstairs934]

thank you so much! this video taught me way more in 10 minutes than my bio teacher has in 2 months

[@sanar3246]

he explains things in a way that instantly gets absorbed in my head... he is good...VERY GOOD!!!

[@melissa_channel236]

Thank you Crash Course! This helped me a lot before my biology exam!

[@tanikhan814]

[@carterkinan]

I like chicken

[@kimberlycaritas]

Hank, it's thanks to you and John that I've passed my science and history classes. Thank you so much for my great sophomore year! My Biology and World History finals await next week, but thanks to you I'm pretty confident. :)

[@lukesinclair-ford4822]

Am I the only one that reads the text book in their head... in Hank's voice and dialect? Just seems to make more sense for some reason.

[@100miloke]

The Years is only a few hours old and I'm already learning. What a great way to start the new year. Oh also Happy New Year Hank and John.

[@Gallifreak]

Thankyou so much. My exam is in ten days, you have no idea how much I needed this

[@timeorspace]

Thank you! This summary is very powerful, and saved me an hour of textbook reading. I appreciate the enthusiastic and tasteful real world applications of this theory.

[@bk7962]

I HAVE AN EXAM TOMORROW AND YOU, SIR, ARE MY SAVIOUR

[@Selichan42_SA]

wow i love watching this six days before the AP exam

[@caseys_gymnastics6355]

I have an Exam in an hour and these videos are saving me 😂

[@OrbGoblin]

I really love these vids. Honestly never cared much about ecology, nor did I think I would find it interesting but I'm enjoying this series quite a bit.

[@jacobf7409]

I literally just watched this in class today. Thanks -.-

[@bleedingsunshine13]

"we pee or poop...or die." well, that took a grave turn

[@waywardplanet]

thank you for making this stuff not boring at all anymore

[@thomaskuzis5665]

Hey Mr. Green I was wondering, I'm a freshman in High School AP Enviornmental Science. Could you make a playlist to help APES students study off of your courses for the AP exam? That would be very helpful ;)

[@skullface215]

Using CrashCourse to study for the AP Environmental AP exam tomorrow!! Thanks Hank!

[@sportsport1654]

I don't how is that possible but you are the only who doesn't make me sleep on this topics

[@97elizabethv]

I'm studying for the AP exam and all I'm seeing is acts, laws and treaties... a Crash Course would be helpful! :)

[@ItoeKobayashi]

I got distracted for about 5 minutes from pressing 2 over and over and watching Hank flap his arms and say "feel it right now"

[@andrewjustin256]

Along with bacteria and symbionts, kudos to the one who created this entire intricately complicated process!!!

[@3Authoress]

I've been an avid follower of SciShow and its extensions so imagine my pleasant surprise when I found out my biology professor decided to use several of these CrashCourse videos as part of her class. KZbin and Science. Beautiful.

[@erinoneill1537]

Honestly, crash courses are so amazing! Not only are they super educational and informative, but they're also very entertaining! Keep up the good work!

[@foreverwantingpie]

I like that I ended the year and started the next looking at Hank's face. It is telling of me.

[@cassidyrich6591]

Bless this man for helping me pass mid-terms

[@Dragonmother52]

Great video! Myccohrizae also make phosphorous available, and they are awesome...don't forget them!

[@hattiemay2272]

*excited face* There it is I can feel it in the air (arms flapping)

[@johnhartney7576]

Thank God for Hank and CrashCourse!

[@jonpro15]

Watching this in class LIVE!

[@paperstarjar]

First video of the new year! Solid start.

[@MHANationTribalHistory]

I came here for the phosphorous cycle spiel but the first 5 mins is valuable information.

[@vasEnterprise]

Anyone else spending New Years alone on KZbin?

[@titansforever1375]

Man this dude talks really quick

[@airro3672]

That's why it's called crash course

[@AdityaFingerstyle]

Not Really

[@headq100]

LMAO right? i think its also the editing tho, they're like omg!!! half a second without him talking!!!! cut that frame out!

[@GoogleEeyes987]

7:08 It's a cycle!! Nice job editing Nick Jenkins, Love it!!

[@livicharette6296]

this channel does exactly what it says crash course. Saving me from staying up all night studying the phosphorus cycle

[@lauralou4594]

You bring joy to my life

[@elaineopal]

Thank you! You helped me study for finals!

[@zavvax]

I wish you were my science teacher. I picked up more in ten minute here than a month in school

[@czrboo]

*Throws my textbook away, opens my iPad and starts watching Hank, wishing he was my teacher* .-.

[@hedgehogpeace]

Happy New Year, Nerdfighteria!

[@abcdoetmee]

thank you!! exams are comming up and it is possible that you just saved me

[@Arithorath]

As a marine reef aquarist, I am extra fascinated by this episode.

[@alpal7322]

these videos are my saving grace

[@debbyflickinger]

Awesome video!

[@millie1594]

You are saving my A level grades for environmental studies

[@Toastwig]

I've been enjoying crashcourse ecology so much! Just wanted to say thanks, it must take a lot of work.

[@065roshnipanjwani8]

Life Saviour... this really helps me to remember things easily.

[@NatoCaloGaming]

It was happy new year for me last night

[@Steve0III]

I just finished my study session for a half an hour break with nothing to do. And this shows up, right on the dot. Huzzah! Boredom held off for a bit. :D

[@strawbyrri888]

I'm doing this for extra credit in science and this is entertaining and very informational..!

[@VidConMom]

Happy New Year to the Vlogbrothers.

[@TheAAbck]

good work.happy new year hank wish you and john green all the best for 2013 and all the other ppl subscribed to ur many channels

[@feldinho]

in portuguese we also use "legumes" as a general term for "vegetables". for most people (at least here in Brazil), legumes are corn, carrots, potatoes and anything else that is vegetable appart from rice, beans (a real legume) or a leaf (those are "verduras").

[@AdamHoskin]

You have just helped me SOOO much for my GCSE's Thank you

[@lloyenscotland2820]

that picture with the many holes just raised up my TRIPPOPHOBIA!!!!!!!!!!!!!!!

[@tarkantakil4719]

Thank you for your input. None of us have ever heard of vsause.

[@TanyaKatherine]

writing a paper on this! Thanks this helped a lot!

[@hixsongarren]

i just played trivia last night and many of the questions in a round about the human body i got because i watched crashcourse biology, so............ thanks!

[@bromaciaolaf5368]

"Nitrogen is awesome and everywhere... and elusive and deserving of your respect." That summarizes my love life.

[@profesorabiologiaanac322]

I love your videos, it so clarity whith you explication , im sorry for may bad inglish XD

[@KidEatingClown]

Who knew I could actually be interested in this stuff?

[@keonablanks6721]

I recommend that you viewers have images of the two cycles on different tabs so you can follow along.

[@teresavanearden7458]

If you burn you garden (after the harvest) will you add more carbon, phosphorous, and nitrogen into the soil for the next year?

[@KevinGullikson]

Hank, when you advertise another video (like the Fritz Haber one here), you should put the link in the doobleydoo and/or show the thing again at the end of the video!

[@aliyahkhan1084]

You helped me ace my ecology final! thank you so much

[@dingdingdingdiiiiing]

this needs alot more love
