Question

1. discuss with your partner reasons why quaternary consumers are rare and there are no higher level consumers. write 1-2 sentences about how available energy in trophic levels limits the length of a food chain. rbio africa storyline

Explanation:

Quaternary consumers are rare because as energy is transferred through trophic levels, only about 10% of the energy is passed on to the next level. By the time you reach the quaternary level, there is very little energy available to support a large population. Higher - level consumers are not present because there is not enough energy in the ecosystem to sustain them. The limited available energy in trophic levels restricts the length of a food chain as there comes a point where there is insufficient energy to support another consumer level.

Answer:

Quaternary consumers are rare due to low energy transfer between trophic levels. Available energy limits food - chain length as it cannot support higher levels.
