Question

Which organisms are greater in number autotrophs or heterotrophs?why

Answer 1

Autotrophs are greater in number. Because they need only natural things, which are available in large quantity, for feeding. Their population increases with fast rate. If we take the example of autotrophic bacteria, we can assume the number of autotrophs. While, heterotrophics are dependent on autotrophs. So their population also directly or indirectly deepens on autotrophics. Also some autotrophs can survive in adverse climate.

Answer 2

Ans: Autotrophs

Explanation:
Plants are autotrophs. They’re are the ultimate source of energy of ALL heterotrophs. If their population decreases, ultimately almost all livings organisms die. But this is not happening at present.
Hence autotrophs are greater in number.
