1. Other than having many features in common, state other characteristics of species 2. Give reasons for the loss of energy from one trophic level to the next in a food chain.

Explanation:

The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.
