Question

Why are there so few ecosystems with more than four levels of consumers?

Answer 1

(a) because biomass decreases by about 90% at each level moving up.

(b) because top consumers compete with and kill each other with increasing population size.

(c) because consumers at these highest levels typically form social groups that stop reproducing at high densities.

(d) because predators at the highest levels simply are not intelligent enough to hunt other top predators

Answer 2

The ecosystem is a system that consists of living organisms, non-living resources, and the physical environment. The ecosystem can be viewed as a pyramid with the top being the largest level which is made up of humans. Humans are considered to be consumers because they use resources for their own needs and then discard them after use. Other than humans, there are very few ecosystems that have more than four levels of consumers. This essay will discuss why there are so few ecosystems with more than four levels of consumers and how this affects biodiversity in an ecosystem.
