On the average, how much energy is lost from each trophic level? explain why

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

I think it's 10% because some of it turns into heat energy

where is the scientific experiment?

condensation. good luck!
