Low concentration to high concentration and requires energy
<h3><u>Answer;</u></h3>
C. Energy is transferred from organisms in one level to those in the level above.
<h3><u>Explanation;</u></h3>
- Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
- 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.
