Second! Hand up if you’re a high schooler that loves this channel?! It’s inspired me to start up on KZbin to help school students as well !! 😁👌🔥

I'm 32 and still enjoy it. Never stop learning! Glad to see people your age taking an active interest in their education (when I was in HS it wasn't socially acceptable to pay attention, lol).

Alex Race Come study with me live on my channel ❤️

[@Romulus_aint_shyt]

I learn better with your videos than listening to my teachers for 1 hour.

[@hepsibaiselvakkani5065]

This is what happens with me too 😉🧐

[@alpharebollar4952]

Mr. Khan, you and all your educational videos are helping me alot thru my collage classes. Thank you.

[@SehrKhan]

Seriously without y'all i'd be failing uni

[@nan0.h]

Wow I clicked fast because I love math or in this case science

[@bonnie_park07]

Thank you so MUCH, you really help me get through my middle school classes. God bless you all!!!

Hey Sal, can you point me in the direction of peer-reviewed articles that refer to the 90% loss of biomass between each trophic transfer? This is relevant to my thesis.

[@ahadofarrah9255]

You still upload videos

[@george6978]

God send video

Trees eat us all in the end...

[@LeonardTheWizard]

I always thought those trees where very fishy.. no wonder they dont move

[@funkmonsterjones4753]

Can you do a video about trophic displacement? I don't know what else to call it, but I see trophic systems as fractal, there are trophic systems embedded within trophic systems and these lines are just human drawn lines, the path from primary producers to apex predator is one continuous field and organisms within the stack hold each other in these check mates like a Nash equilibrium. Got any material like this?

[@sauradeepdas1080]

Then how we humans fit in this pyramid..I suppose we are the level 5

[@combineadvisor572]

Yay more Salman Khan

How many times do we need to consume a quaternary consumer to gain 20,000kcal/m²/yr?

[@Classic--]

or doing what ever.. exactly!

[@enanxahmed]

Illuminati Confirmed!

[@spencerparkinson9973]

Wouldn't the apex predator be capable of hunting from mulitiple levels of the pyramid allowing it to grow more than the 10% projection
