That’s cool, hey Kahn, I’m in 5th grade, and your videos have been a very big help to me all year.
I have a khan academy account but so many people post in those comments my comments are most likely never seen, so I go here to thank you. And keep up the great work your doing, because it’s really a big help.

Good video although some points are wrong.
Firstly the arrows show flow of energy not what eats what. Secondly in the food chain grass—> grasshopper—> Hawk—> coyote the coyote is a tertiary consumer, it’s designation depends on the number of trophic levels in the food chain, in some cases the coyote may be secondary in others it’s tertiary.
Finally toward the end you say coyote eats the vulture, I’m sure you mean vulture eats coyote as the arrow shows the energy flow from coyote to vulture.
