Answer 1

The correct response is:

**because energy is lost to the environment as heat between levels**

This concept is commonly referred to as the "10% rule" in ecology, where only about 10% of the energy from one trophic level is transferred to the next due to energy losses (primarily as heat) in metabolic processes and other activities.
