What is the maximum number of trophic levels an ecosystem can support?

Answer 1

No more than five trophic levels are present in an ecosystem, most have only 4.

In all ecosystem, first base level of pyramid will be occupied by producers, consumers occupy higher trophic levels. Energy is lost when it is transferred from one trophic level to the next. Approximately 10% of the stored energy of a trophic level could be transferred to the consumers of next level. Thus very less number of individuals could be supported at the top level.

In a four level pyramid, only 0.1% of fixed energy ultimately reaches the top.

Normal trophic levels are often only 4/5 organisms long as much of the energy is lost between levels.

The maximum number of trophic levels an ecosystem can support is typically around five, due to energy loss as it moves through each level.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
