Question

If the earth were without any autotrophs what would happen to rest of the life. Explain?

Answer 1

See below.

Explanation:

If Earth had no autotrophs, this would mean that the heterotrophs that ate the autotrophs (Ex: a cow eating the grass) would have nothing to eat and would die off which means that if heterotrophs dies off, then humans would eventually die due to nothing to eat unless something is edible.
