Question on: SS2 Biology - Nutrient Cycling In Nature
Explain the carbon cycle in detail. How is carbon exchanged between the atmosphere, living organisms, and the Earth's crust?
The carbon cycle is a complex process that involves the exchange of carbon between various reservoirs. Carbon dioxide in the atmosphere is taken up by plants through photosynthesis, converting it into organic compounds. This carbon is then passed through the food chain as organisms consume plants or other animals. Carbon is eventually released back into the atmosphere through respiration and decomposition. Additionally, carbon is stored in the Earth's crust as fossil fuels, which can be released through combustion. The cycle continues as carbon is continuously exchanged between these reservoirs.
