Describe the carbon cycle, including its main reservoirs, processes, and human impacts.

i)

• A: Producers / Plants
• B: Atmospheric Carbon Dioxide
• C: Consumers / Animals
• D: Decomposers / Dead organic matter

ii)

• P: Photosynthesis
• S: Fossilization / Decomposition
• T: Combustion / Industrial emissions

iii) Three activities of humans that could disrupt the cycle are:

• Burning of fossil fuels (e.g., in power plants, vehicles) which releases large amounts of carbon dioxide into the atmosphere.
• Deforestation, which reduces the number of plants available to absorb carbon dioxide through photosynthesis.
• Industrial activities that release carbon dioxide and other greenhouse gases as byproducts.
