Question

Chemical energy input converted from the sun occurs via (respiration/photosynthesis) n plants or ingesting food in animals. This energy drives the flow of matter into and out of the cell. The chemical energy is inefficiently converted into usable energy by (respiration/photosynthesis) , because all of the stored energy is not converted into ATP. Some of it is released into the ecosystem as
(heat/waste)

Answer 1

Chemical energy input converted from the sun occurs via **photosynthesis** in plants or ingesting food in animals. This energy drives the flow of matter into and out of the cell. The chemical energy is inefficiently converted into usable energy by **respiration**, because all of the stored energy is not converted into ATP. Some of it is released into the ecosystem as **heat**.
