Question

The importance of an ecosystem lies in

• A. Flow of energy
• B. Cycling of nutrients
• C. Both (A) and (B)
• D. None of the above

Answer 1

Answer: (C)

Both (A) and (B)

The ecosystem is responsible for the flow of energy as the autotrophs convert the light energy provided by the sun to chemical energy which is further consumed by heterotrophs. In this way energy transferred from plants to herbivores and from them to carnivores.

When the complex organisms die, they are consumed by the bacteria and fungi, which are the decomposers, which break down the complex substances into simple inorganic forms. Thus, the cycling of nutrients takes place.

Since, both the statements in options (A) and (B) are correct, option (C) is the correct answer.
