Hank describes the desperate need many organisms have for nutrients (specifically nitrogen and phosphorus) and how they go about getting them via the nitrogen and phosphorus cycles.

excited face There it is I can feel it in the air (arms flapping)
"bet your face"
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!
7:45 fertilizers
6:25 then it gets into the water…can be caught in cycle for 100K years
You’re a poop from a butt
It feels so slow once you go back to 1x speed after experiencing 2x speed for these videos
Nice, thanks for this fun form of education people about ecology. I was taught the other day that phosphorus can be in the atmosphere…because in anaerobic soil conditions, it can turn into phosphine gas. In fact, it can be seen at night rising from the ground in a yellow-green mists…for example from decaying bodies in a graveyard (pre-modern burial methods). Is this true? Was I misinformed?
So yall just eat carrots without a thought? Woah there Bugs
"iT's a CyCLe"
This dude be the science version of eminem
Any one else just realize his name is hank
Video starts at 1:46
Thank you.
Thank God for Hank and CrashCourse!
I reduced the speed to .75 and understand EVERYTHING now mwahaha
I dislike all of his videos
You're brilliant, but you speak so quickly!
"Phosphorus wants nothing to do with your air" Love it
If anyone has any tests tomorrow best of luck! 😂👍🏻
subscribing to your channel, explanations aren’t boring and dull and visuals help too 👌
In the commercial, Barbie is swimming. Is she a part of the cycles too 🤔
hes so fresh
IT'S A CYCLE
Sir thanks you are greatest one
thank you SO much This helped me so much!!!!!!!
Who else has to do this for school?
i still dont get this
can someone explain the nitrogen and carbon cycles for me? im really, really lost.
Just to remind people that organic nitrogen is very abundant in the soil and can be taken up by plant roots (without the need of symbiotic associations) in the form of peptides.
You helped me ace my ecology final! thank you so much
Who else is studying late at night
1:14 cant we just drink mineral water guys
Test in 3 hours RIP
DOES ANYONE ELSE HEAR A QUIET PHONE RINGING WHENEVER YOU PLAY THE VIDEO??????
5:21 phosphate cycle

Sorry but you speak really fast
Never thought I would use crash course in sophomore year of college
