Why can food chains
lana66690 [7]

Answer:

A. Because energy is lost at every level.

Explanation:

energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.

Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).

This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.

Hope this helps, have a lovely day :)
