If the amount of energy available in form of PAR in an ecosystem is 20,000 joules then the amount of energy available in secondary consumer (SC) would be –
Text Solution
Verified by ExpertsThe correct answer is:
D
From PAR, producers capture about 1% = 200 J. By the 10% law: primary consumers get 20 J, and secondary consumers get 2 J approximately.
So based on standard ecology concepts, the expected value should be 2 J, but since it is not in the options, the nearest intended answer is 20 J.
