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.

Why is the biosphere important in the carbon cycle?

Back

The biosphere contains all living organisms on Earth, which play a crucial role in the carbon cycle by taking in and releasing carbon.

Front

What happens when fossil fuels are burned?

Back

Burning fossil fuels releases carbon dioxide into the atmosphere, contributing to climate change.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, including the crust and upper mantle, where fossil fuels can be found.
