- Hello sir/miss, the question and answer are provided below. Is the answer to the question correct? Explain how the carbon cycle is related to energy flow in ecosystems. As organic molecules are produced by joining and reducing carbon atoms, energy is stored in them. This is done by producers or plants. Then, when these molecules are broken down and carbon is oxidized, energy is released, this is called cellular respiration or burning. Carbon dioxide is emitted into the atmosphere and absorbed from the atmosphere when this occurs.arrow_forwardPhotosynthesis is the basis for food production on Planet Earth.

C) there is a large sedimentary pool of phosphorus. D) there is no limiting step in the phosphorus cycle.arrow_forward

They decompose and create fossil fuels after death. They use carbon dioxide from the atmosphere during photosynthesis. They supply the light energy that makes photosynthesis possible.
