Back

True

Front

What can happen to organisms that do not decompose?

Back

They can be buried and become fossil fuels.

Front

During photosynthesis, carbon is moved from which reservoir to which reservoir?

Back

From the atmosphere to the terrestrial biosphere.

Front

What is the relationship between plants and animals in the carbon cycle?

Back

Plants produce and release oxygen that animals need.

Front

How does carbon get from the atmosphere into organisms?

Back

Through the process of photosynthesis.

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 carbon dioxide and water.

Front

What role do decomposers play in the carbon cycle?

Back

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

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which organisms convert oxygen and glucose into energy, releasing carbon dioxide back into the atmosphere.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, primarily composed of carbon, and used as energy sources.
