Question

Read the following statements carefully:
(I) Energy transfer in the biotic world always proceeds from the autotrophs.
(II) Energy flow in unidirectional.
(III) Energy availability is maximum at the tertiary level.
(IV) There is a loss of energy from one trophic level to the other.

Select the relevant statements for a forest ecosystem.

• A. I, II and IV
• B. I, II and III
• C. I, III and IV
• D. II, III and IV

Answer 1

The correct option is A I, II and IV

A forest ecosystem is formed by the community of organisms which live in a forest. The relevant statement for the forest ecosystem are:

• Energy transfer in the biotic world always proceeds from the autotrophs as the plants and the trees are the major producers.
• Energy flow is unidirectional.
• There is a loss of energy from one trophic level to the other as the law of energy transfer is applicable to this ecosystem.

So, the correct answer is option A.
