Detailed explanation-1: -Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.

Detailed explanation-2: -In this activity, students explore the role of combustion in the carbon cycle. They learn that carbon flows among reservoirs on Earth through processes such as respiration, photosynthesis, combustion, and decomposition, and that combustion of fossil fuels is causing an imbalance.

Detailed explanation-3: -Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere.

Detailed explanation-4: -Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.

Detailed explanation-5: -Combustion is occurring where the tree is releasing carbon dioxide, water, and smoke into the air. All the other processes – growth, uptake of water and minerals by plants, decay, and defecation-are powered by cellular respiration. Explain: All of these processes, put together, are called the Carbon Cycle.
