Front

What process do plants use to make their own food?

Back

Photosynthesis, which involves using sunlight, carbon dioxide, and water.

Front

What is the role of decomposition in the carbon cycle?

Back

Decomposition returns carbon back into the atmosphere by breaking down dead organisms.

Front

What can happen to organisms that do not decompose?

Back

They can be buried and become fossil fuels over time.

Front

What do animals take in during respiration?

Back

Oxygen.

Front

What do animals release during respiration?

Back

Carbon dioxide.

Front

What process does NOT produce carbon dioxide?

Back

Photosynthesis.

Front

What is the primary gas that plants absorb during photosynthesis?

Back

Carbon dioxide.

Front

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels store carbon that can be released into the atmosphere when burned.

Front

How does the burning of fossil fuels affect the carbon cycle?

Back

It increases the amount of carbon dioxide in the atmosphere.

Front

What is the relationship between respiration and photosynthesis?

Back

Respiration releases carbon dioxide, which is used by plants in photosynthesis.
