E) the rock cycle.

Question

Quizplus · Accepted Answer

Transfer of carbon between organisms primarily occurs through the processes of photosynthesis and cellular respiration. Plants take in carbon dioxide through photosynthesis and use it to make organic compounds, which are then eaten by other organisms. During cellular respiration, organisms break down organic molecules to release energy, producing carbon dioxide as a byproduct. This carbon dioxide can then be taken up by other organisms for photosynthesis, completing the carbon cycle.
