In an ecosystem, the flow of energy is

Options

A. Bidirectional
B. Cyclic
C. Unidirectional
D. Multidirectional

Answer

C

Explanation

The enetgy enters the plants from the sun through the photosynthesis process. This energy is then passed on from one organism to another in a food chain. The flow of energy in the ecosystem is unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. during the transfer of energy through successive tophic levels in an ecosystem, there is loss of energy all along the path.
