Best answer
Correct answer is (d) The rate of energy flow through the food chain

The explanation: The pyramid of energy is said to be the best representation of an ecosystem because it indicates the rate of energy flow through the food chain. Depending upon the nature of the food chain, the pyramid is always upright.
