Explanation:
Energy gets transferred from one trophic level to another when an organism consumes the organism below it on the trophic level pyramid. However, most of the energy is lost at each trophic levels. Ecologists have made observations and illustrated that only 10% of energy gets transferred from one trophic level to another.
For example, let's consider the energy in producers to be 100%. the energy transferred by them to the primary consumers will be 10%. The energy transferred from the primary consumers to secondary consumers will be 1%.
