Question

If 2000 kcal of energy are available in grass, how much energy would be available to the cow that eats the grass? To the Human that eats the cow?

Answer 1

If 2000 kcal of energy are available in grass, a cow eating that grass would receive approximately 200 kcal of energy, and a human eating the cow would receive roughly 20 kcal, as only about 10% of energy transfers from one trophic level to the next in a food chain

Answer 2

that would be about 6800 kcals

Answer 3

My brain is too young for dis kinda stuff -_-

Answer 4

Cow: 2000 kcal (grass) x 0.1 = 200 kcal
Human: 200 kcal (cow) x 0.1 = 20 kcal
