Question

Which of the following statements describes one way that energy flows out of an ecosystem?

Answer 1

Answer:

Cellular respiration produces heat as a by-product, and this heat dissipates into the atmosphere

Explanation:

The energy in the ecosystem is obtained mainly from the Sun, by conversion of the Sun's energy into energy rich molecules from which chemical energy can be obtained through cellular respiration in other living organisms, a process that produces heat as a byproduct.

The chemical energy is then converted into kinetic energy and heat energy, as a byproduct, within the cells of the muscular system. The heat is transferred out of the body of an organism into the atmosphere and environment and from there to other remote locations away from the ecosystem, through conduction, and convection, leading to a flow of energy out of the ecosystem
