NITROGEN CYCLE: A level biology AQA. Saprobionts, nitrogen-fixing, ammonification & nitrification

[@abikage]

last bit left to consolidate before paper 2 tomorrow, thank you so much.

[@laurenm7832]

Thank you so much for this, please keep going despite not getting as many likes/views as the big channels like snap revise etc. - it's a growing channel and you really are making a difference, your work is really appreciated! :)

[@MissEstruchBiology]

Thank you Lauren. Really pleased to making a difference and helping 😊

[@uwotm8770]

she's way better than snaprevise and tailored tutors imo too

[@jessekenzo8700]

i know it is pretty randomly asking but do anybody know a good site to watch new movies online?

[@jessekenzo8700]

@Jesiah Tyson thanks, signed up and it seems like a nice service :D Appreciate it !!

[@jesiahtyson6646]

@Jesse Kenzo no problem =)

[@joshuamensah9309]

Science content from school is so superficial. They have intentionally misplaced or discarded the majority of vital and valid scientific information. This is things seem so vague for me in class and don't make much sense, that's because they're not true. Thankyou for this video it has explained the concept the right way in an amazing manner.

[@MissEstruchBiology]

Glad it helped!

[@jasminea6740]

Revising for a test I have next week and your video is so helpful! You've gained a new subscriber! 👍

[@MissEstruchBiology]

Yay! Thank you! Best of luck for your test.

[@galefray]

Another day, another fantastic Miss Estruch video.

[@MissEstruchBiology]

☺☺ thank you so much

[@mdahmed9079]

Ohh God! This is the perfect explanation and diagram to represent the nitrogen cycle, sadly my text book and my teacher could never explain this cycle as simple as you did, keep going

[@MissEstruchBiology]

Ahh so glad you found easier to understand!!!

[@ovandobowen850]

Not manny ppl can explain nitrogen cycle so understandable

[@MissEstruchBiology]

thank you! Hope it helps you 😊

[@markbenn1907]

really good explanation. Perfect amount of info for probably 95% of people.

[@MissEstruchBiology]

Glad you found it helpful

[@saidurrahman3683]

this is literally the perfect explanation☺

[@MissEstruchBiology]

awww yay!!! So glad it helped

[@candicexo1725]

This was so helpful thank you so much x

[@MissEstruchBiology]

Glad it was helpful! :)

[@joanniemaegalupan575]

My exams would be 2days to go.. this one is so helpful as to refresh.. thanks

[@ajtv6208]

Your videos are amazing - really appreciated

[@ameenanaeem741]

Good perfect ma'am ❤

[@morganreed726]

cheers mate really helpful hope i pass!!!!!!!

[@MissEstruchBiology]

Good luck!

[@arghon752]

we have a presentation about this and this was sooo helpful! thank you very much !

[@MissEstruchBiology]

ah that's great. I hope the presentation went well!

[@user-zt1dy8ny9g]

Best teacher thanks I understood this and never forget now

[@MissEstruchBiology]

You're so welcome!!

[@digio1482]

Excellent presentation!

[@MissEstruchBiology]

Thanks!

[@georgemoutafis4399]

@@MissEstruchBiology you are welcome. Sorry for the late reply. I just saw your message.

[@DomsFillums]

Excellent overview. Please can you get a job that the OU and whip all their rambling fluffy year 3 material into shape? In 9 minutes you explain what they can't quite get around to in an entire chapter.

[@MissEstruchBiology]

🤣🤣 thank you 🙈 So pleased you found concise and easy to follow!!!

[@Sedasedaking]

I would like to ask for questions about nitrogen cycle please

[@RoseWhitehead-mx8od]

Is it right that ammonification only happens when it is converting nitrogen from dead organisms, waste products etc into ammonium and this is only done by saprobionts. Whereas nitrogen fixation occurs only when it is from nitrogen in the atmosphere converted into ammonium and this is only done by bacteria. This would mean that bacteria cannot carry out ammonification?

[@samsmithard1900]

Hey is the relationship between bacteria and legumes mutualistic? I understood that mutualism and symbiosis were two different things

[@MissEstruchBiology]

Yes it is 😊

[@danix6452]

I have seen the process in different orders such as nitrogen fixation as last instead of denitrification and am really confused on which one to follow, which one is correct and does it matter the order?

[@MissEstruchBiology]

Hey, it is a cycle, so there is no start or end stage so it doesn't matter. I hope that helps 😊😊

[@telegnes4500]

Love your work. Keep it up.

[@MissEstruchBiology]

Thank you 😊 So glad you like it.

[@dylangiblin6394]

Thanks for that darlin x

[@atrappy2077]

bit embarrassing calling a teacher that, cmon do better🤦‍♂

[@MatT-vf7qo]

can ammonification also be where nitrogen fixing bacteria converts nitrogen gas into ammonium

[@MissEstruchBiology]

Hello, Whilst this stage can result in the production of ammonium, that stage is classed as nitrogen-fixing, rather than ammonification as it this is when N gas in the atmosphere is fixed into an N-containing compound, which might be ammonia.

[@onepumpkid3504]

At 4:00, would we not call that step nitrogen fixation instead of ammonification?

[@ChanceChelios]

So lets say I start a new soil in pots/raised beds, would i have to grow a cover crop crimson clover “Legumes” , sow it, covering it with compost creating “green manure” so it will then have Rhizobia “nitrogen fixing bacteria” already bio available in the soil for that symbiotic relationship for the next cover crop? would it already be bio available for any crop available ,Or would I still have to plant a second grow of Crimson clover, in the same bed to help make nitrogen bio available for the Main crop you’re growing?

[@atrappy2077]

4:00 , nitrogen into ammonium from nitrogen fixing bacteria in soil. is that nitrogen fixing or ammonification ?

[@mdrayyan1831]

Very nice

[@MissEstruchBiology]

Thanks

[@katielong4437]

girlboss

[@mackerel9875]

3:56 does ammonification convert atmospheric nitrogen into ammonium? i thought it converted nitrites into ammonium.

[@MissEstruchBiology]

Hello Ammonification more refers to ammonium produced from the death and decay of organis matter ( e.g proteins)

[@alexandra129]

what is the order of the these processes? like what happens first

[@porcupineou]

its a cycle so theres no “first”, they all occur at the same time in different areas, just learns what leads to what and youll be good

[@joshuamensah9309]

And didn't you mean to say Ammonium instead of Ammonia at 5:59 ?

[@MissEstruchBiology]

hello, yes, ammonification results in ammonium being production.

[@spikedmini1234]

I thought clover was a leguminous plant?

[@spikedmini1234]

3:40

[@MissEstruchBiology]

Hello, Yes it is, I perhaps didn't phrase it clearly. I meant 'if it is not a leguminous plant, and clover and beans plants are examples of leguminous plants' Hope that helps :)

[@nikta3679]

at 3:26 are you referring to mycorrhizae ? So only legumenes plants have mycorrhizae?

[@redvelvetcarrots]

this saved my life, i have a quiz tomorrow😅😅

[@MissEstruchBiology]

eeek good luck!!!!
