If the grass in this example had 10,000 Kcal of energy, about how much of that energy would be stored in trophic level 3?

Back

About 100 Kcal of energy would be stored in trophic level 3, following the 10% energy transfer rule.

Explain the 10% rule in energy transfer.

Back

The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next level, with the rest lost as heat.
