Question

In an ecosystem [AIEEE 2004]
A) Cycling of energy and nutrients is a coupled process
B) Cycling of energy is an independent process
C) Movement of energy is unidirectional
D) Macro and micronutrients cycle at the same pace

Answer 1

In an ecosystem
➡️ Cycling of energy and nutrients is a coupled process

Answer 2

In an ecosystem the A) Cycling of energy and nutrients is a coupled process.  

This is because the cycling of nutrients and energy in an ecosystem occurs hand in hand as side by side process. The cycling of both these components keep the ecosystem functional.  

The absence of one component also will lead to the fall of ecosystem. To achieve proper development of organisms proper cycling of energy and nutrients is required.
