Question

Explain the transfer of energy in organisms at different trophic levels?

Answer 1

Secondary consumers: Organisms which obtain energy by consuming primary consumers. They are carnivores. Decomposers: These organisms form the end point of every food chain. They are bacteria or fungi that obtain their energyby breaking down dead organisms from the other trophic levels.

Answer 2

A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
