Question

choose the correct answer.
why are there fewer top - level predators compared to primary consumers?
top - level predators rarely add to the population.
there is less available energy at higher trophic levels.
all top - level predators have specific prey to hunt.

Explanation:

In an ecosystem, energy transfer between trophic levels is inefficient. Only about 10 - 20% of energy is passed on to the next level. As top - level predators are at the highest trophic levels, there is less energy available to support a large population compared to primary consumers at lower trophic levels.

Answer:

B. There is less available energy at higher trophic levels.
