Question

The number of organisms in a food pyramid decrease as the trophic level A) decreases.  B) increases. C) stays constant. D) changes unpredictably.

Answer 1

Decreases

Step-by-step explanation:

because there is less energy available to support those organisms. The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.

Answer 2

Answer: B) increases.

Step-by-step explanation:

A food pyramid is a diagrammatic triangular representation of the food and energy distribution among different organisms belonging to different trophic levels. The flow of energy is unidirectional this because of the fact that organisms of the lower trophic levels are consumed by organisms of higher trophic levels. The number of organisms at the lower trophic levels are expected to be more so that they can meet the food and energy needs of organisms of higher trophic levels.

Hence, The number of organisms in a food pyramid decrease as the trophic level increases.
