Use the information in the paragraph below to answer the following question. In a small pond, green algae grows near the surface of the water to the depth that light penetrates. Algae need the light to photosynthesize. Tadpoles and small fish feed on the algae. Bigger fish and turtles feed on the tadpoles and smaller fish. When the organisms die, they fall to the bottom of the pond where bacteria and fungi decompose their bodies. What process do all of the organisms use to release energy for metabolism?
A. Cellular respiration
B. Decomposition
C. Photosynthesis
D. Production
