Plants and trees take in carbon dioxide for photosynthesis.
Why is the water cycle important ?
As it provides fresh water for the animals and plants on land.
What is the role of photosynthesis in the carbon cycle ?
During photosynthesis, plants absorb carbon dioxidde and sunlight, to create fuel and other sugars.
What is the role of respiration in the carbon cycle ?
Respiration is the process in which carbohydrates are converted to water and carbon dioxide, so that carbon is released again into the air.
What is the role of combustion in the carbon cycle ?
Combustion occurs when something is burned, such as fossil fuels, to give off carbon dioxide and energy.
