(c) Amount of vacuum in the universe

(d) Quality of energy used by green plants for photosynthesis

I had been asked this question at a job interview.

Answer 1

Correct choice is (b) Quantity and path of energy flow from producers to consumers

Explanation: In ecological energetics (production ecology) we study the quantity and path of energy flow from producers to consumers. It is the amount of energy that entered in a living system until it is ultimately degraded to heat and is lost irreversibly from the system at a specific time.
