Verified step by step guidance1
Understand the concept of energy transfer in a food chain: Energy is transferred from one trophic level to the next, but not all energy is passed on.
Recognize that energy is lost at each trophic level due to metabolic processes, heat loss, and other factors.
Learn the '10% rule' in ecology, which states that typically only about 10% of the energy from one trophic level is transferred to the next level.
Consider the options given: 75%, 50%, 25%, and 10%. Compare these with the 10% rule.
Conclude that the correct percentage of energy transferred to each higher trophic level is typically 10%, based on the 10% rule.
