Which of the following statements are Correct?

a. Energy flow from producers to consumers is unidirectional

b. Energy pyramid can never be inverted

c. Transfer of energy follows the 1% law

Choose the correct answer from the options given below:

Options

A.a and c only
B.b and c only
C.a, b and c
D.a and b only

Solution

Sol. [Key Concept: Evaluating the correct statements]

Energy flow is unidirectional. First plants capture solar energy and then, food is transferred from the producers to decomposers.

Pyramid of energy is always upright. It can never be inverted, because when energy flows from a particular trophic level to the next trophic level, some energy is always lost as heat at each step.

The transfer of energy follows 10 per cent law - only 10 per cent of the energy is transferred to each trophic level from the lower trophic level.
