Text Solution

Verified by Experts

The correct Answer is:
B
There are generally a greater number of individuals at the lower trophic levels of an ecosystem, the greatest number is of the producers. The flow of energy in an ecosystem is always linear or unidirectional. The energy captured from producers does not revert to the solar input. Also, the energy which passes to the herbivores does not come back to autotrophs.
