What is the carbon cycle?

Back

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.

Front

What role do plants play in the carbon cycle?

Back

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

Front

What is cellular respiration?

Back

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

Front

What is a primary consumer?

Back

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

Front

What is a secondary consumer?

Back

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

Front

What is a decomposer?

Back

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

Front

How does carbon move through the food web?

Back

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

Front

What is photosynthesis?

Back

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.

Front

What happens to carbon during decomposition?

Back

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

Front

What is the significance of gas exchange in the carbon cycle?

Back

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.
