The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes like photosynthesis, respiration, and decomposition.

Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into organic matter, which is then passed through the food web.

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, releasing carbon dioxide and water as byproducts.

A primary consumer is an organism that eats producers (plants) to obtain energy, typically herbivores.

A secondary consumer is an organism that eats primary consumers to obtain energy, typically carnivores.

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the soil and releasing carbon dioxide.

Carbon moves through the food web as organisms consume one another, transferring carbon from producers to primary consumers and then to secondary consumers.

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

During decomposition, carbon stored in dead organisms is released back into the atmosphere as carbon dioxide, contributing to the carbon cycle.

Gas exchange is crucial for the carbon cycle as it allows organisms to take in carbon dioxide for photosynthesis and release oxygen, while also allowing respiration to release carbon dioxide.
