Question

Quizplus · Accepted Answer

In accordance with the second law of thermodynamics, most of the energy in an ecosystem is eventually converted to heat and released into the environment. This heat energy may be transferred from one organism to another or radiated into space, but ultimately it cannot be converted into other forms of energy to sustain life. Therefore, choice D that the ultimate disposition of most energy in an ecosystem eventually returns to space in the form of heat is the best choice.
