Aquaternary consumer species would be expected to have a smaller population than a secondary consumer species

Answer;

The above statement is true

A quaternary consumer species would be expected to have a smaller population than a secondary consumer species.

Explanation;Energy in a ecosystem decreases as you move from one energy level to another therefore the number of species will decrease as the energy decreases as you move up the trophic levels.Therefore, secondary consumers will have a smaller population than that of primary consumers as primary consumers receive more energy than the secondary consumers. Hence, the same applies form the quaternary consumers, their population is smaller than that of the secondary consumers.
