Question

in an ecosystem, organisms use up chemical energy. what is most of the energy then lost to the environment as? photons heat light

This is in line with the second law of thermodynamics, which states that energy transfer is not 100% efficient and some energy is always dissipated as heat.

Answer:

heat
