Question

in the ecological pyramid diagram, which trophic level has the least amount of energy available? select one answer.
primary producers
primary consumers
secondary consumers
tertiary consumers
apex predator

Explanation:

In an ecological pyramid, energy decreases as we move up trophic levels. This is due to the 10% energy transfer rule (most energy is lost as heat or used in metabolism). The apex predator is at the top of the pyramid, so it has the least energy available.

Answer:

APEX PREDATOR
