Solution Steps

Step 1: Analyze the diagram

The diagram shows the carbon cycle, which is the process by which carbon moves between the atmosphere, land, and ocean. Plants play a role in the carbon cycle through photosynthesis and respiration.

Step 2: Photosynthesis

Plants absorb carbon dioxide from the atmosphere during photosynthesis. They use this carbon dioxide, along with water and sunlight, to create organic carbon, such as sugars, which they use for growth and energy. This process removes carbon dioxide from the atmosphere and stores it in plant tissues.

Step 3: Respiration

Plants also release carbon dioxide back into the atmosphere through respiration. This process, which also occurs in animals, breaks down organic carbon to produce energy, releasing carbon dioxide as a byproduct.

Step 4: Plant decay

When plants die and decay, the organic carbon in their tissues is broken down by decomposers, releasing carbon dioxide back into the atmosphere and soil. Some of this carbon may be converted into fossil fuels over long periods.

Final Answer

Plants take in carbon dioxide during photosynthesis and release it during respiration. They also contribute to the carbon cycle when they decay.
