Man I wish I was in your biology class. I have looped this video and I get smarter each time it plays.

[@BWatsy]

My dad once told me that if you can't explain something simply, you don't understand it well enough to teach. I applaud your ability to strip these seemingly complex concepts down to their essence. Coming from an engineering student whose most apparent knowledge gap is biology, thank you very much for putting all of these videos together. You'll soon have +1 views to all of your videos :)

[@lisaa.harwood5043]

A REALLY GREAT VIDEO. I USE THIS FOR MY CLASSES.

[@AAA11546]

VERY helpful. In class I found this quite difficult. Your clear steps and visual presentation made it suuuper easy. Thanks again :))

[@BeverlyBiology]

Glad I could help.. thanks for watching

What is the problem with the bonding of two nitrogen atoms ?

[@Hippieheyhey]

I would say it wants to stay in that triple bond, it does not want to break free. When free, it gets the chance to bond to Hydrogen atoms etc forming nitrite then nitrate. Nitrogen in the converted form can then finally be used by bacteria in soil/plant/animals.

[@ChanceChelios]

Dumb question, does snow bring down nitrites too, for the soil?

[@valentinengatchayokeu2971]

yes

[@charliehalsey6251]

In another video i've seen on the nitrogen cycle it says that nitrogen fixation converts N2 into Ammonia not ammonium, please can you explain the difference, thanks!

[@the81kid]

I haven't finished studying it all, but ammonium is NH_4 while ammonia is NH_3. Ammonia is a weak base, when it's ionized it becomes ammonium. So maybe it depends on the pH of the soil?

[@charliehalsey6251]

@@the81kid I really don't know man, haha I hope it all means the same thing lol

[@persea1000]

Hi er cror

[@the81kid]

Many thanks!

[@sulamit9386]

this is such a good video of explaining the nitrogen cycle. I have a question for step 5 and 6 why aren't we using nitrates ?

[@brandonanders6364]

at 3:20, denitrification shows a release of "N", should this be "N2" to complete the cycle? There's no comment about it.

[@pn3132]

dont caere

[@anji962]

The two N will form N2

[@sabrinawang302]

ive googled so many of these vids, but ur honestly an amazing teacher :))

[@sabrinawang302]

hi, i just read my textbook, and this is what it says: - Nitrogen fixation (N2 to NH3/ NH4+ or NO3-) - Nitrification (NH3 to NO3-) - Assimilation (Incorporation of NH3 and NO3- into biological tissues) - Ammonification (organic nitrogen compounds to NH3) - Denitrification(NO3- to N2)

What can I do to change his language

[@eswaranki5411]

Awesome Job, you did it, to understand in easy way. Once again heartfelt thanks to you

[@naryanipranju]

Thanks a lot for the video. May I ask you for a favor? Can you please do a video on Oxygen Cycle

[@BeverlyBiology]

You will find a short review of the oxygen cycle if you fast forward to 6:20 of this video. kzbin.info/www/bejne/baDPemWbnamiqdU

[@beyondeverything2722]

Thank you so much

[@dami4271]

What about nitrites?

[@khushikaur5347]

Thanks, that helped me a lot!!!:)

[@BeverlyBiology]

You're welcome... best wishes to you.

[@greenawesome35]

Thank you!

[@BeverlyBiology]

+greenawesome35 Glad to help.. best wishes to you.

[@roseoladunjoye4863]

can u do a carbon cycle

[@BeverlyBiology]

+rose oladunjoye I have a Carbon cycle video... here is the link: kzbin.info/www/bejne/hXi5Yo1tZ7lpr8U

[@niarsyad]

How I wish you were my biology lecturer T_T

[@BeverlyBiology]

+Munirah Mokhsin You say that now... but if you were my student you might feel differently. Ha Ha. Best wishes to you.

[@niarsyad]

+Beverly Biology hahaha then i shall just stick to watching and listening from youtube 😂 oh and thank you!

In Quran, God mentioned, Surah Al Hijr [15:22]: And We have sent the fertilizing winds and sent down water from the sky and given you drink from it. And you are not its retainers.
