Carbon is returned to the atmosphere through respiration of plants and animals. The correct answer is B.
In the carbon cycle, carbon is released as carbon dioxide through the atmosphere to the living organisms which is then moved or transferred from one living thing to another and returned as carbon dioxide back to the atmosphere.
<h2>Further Explanation</h2>
During photosynthesis, the green plant uses carbon dioxide, which also forms part of the complex molecules (carbohydrates, fats, and protein)
When plants are consumed by animals, they received carbon from the plant which also serves as energy.
However, carbon is released back to the atmosphere through the respiration of plants and animals.
Carbon dioxide is used by photosynthetic organisms and it is a very vital element in the body of the living organism. The living organism also use carbon dioxide to form organic molecules
Respiration in plants: just like animals, energy is also important to plants. They get their energy through respiration and which is used by the plant to perform different life processes. During the process of respiration, they receive oxygen from the air, use for energy and releases carbon dioxide as a by-product.
However, in Cellular respiration, animal breathes in oxygen and releases carbon dioxide.
Therefore, carbon is returned to the atmosphere through respiration in plants and animals.
