Answer:
1. The exchange of carbon between organisms and the environment: The carbon cycle involves the transfer of carbon between living organisms and their surroundings.
2. Photosynthesis and cellular respiration moving carbon through the atmosphere: Photosynthesis removes carbon dioxide from the atmosphere as plants convert it into glucose and release oxygen. Cellular respiration releases carbon dioxide back into the atmosphere as organisms break down glucose for energy.
3. How organisms store carbon: Organisms store carbon in their tissues as organic compounds like carbohydrates, proteins, and fats, created through photosynthesis or consumption of other organisms. Some carbon is stored in soil as organic matter, while some may become fossilized over time in the form of fossil fuels.
