Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon back into the atmosphere as carbon dioxide.

Front

How do fossil fuels contribute to the carbon cycle?

Back

Fossil fuels release carbon dioxide into the atmosphere when burned, contributing to the greenhouse effect.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.
