All living things need energy to perform their life processes. how and where do they get the energy that they need? a. the production of carbon dioxide through the process of photosynthesis b. the absorption of light that radiates from the moon c. the oxidation of food through the process of cellular respiration d. the fixation of nitrogen gas from the atmosphere

RE: "A."

Plants get energy from the sun (photosynthesis), but the production of Carbon Dioxide does not give any living thing the energy to perform their life processes.

RE: "B."

The Moon's reflective light does not give any living thing the energy to perform their life processes.

RE: "C." [Best answer]

The breakdown of food does give any living thing the energy to perform their life processes.

RE: "D." Plants' roots "fix" Nitrogen gas from the atmosphere, but that does not give any living thing the energy to perform their life processes.

answer is d hope this
