Quick Check: Carbon Cycle Review

Front

What is the primary way animals obtain carbon?

Back

Animals obtain carbon by consuming or eating plants or other animals that contain carbon.

Front

How does carbon move between the atmosphere and oceans?

Back

Carbon can move back and forth between the atmosphere and oceans by dissolving.

Front

Which sphere of the Earth contains carbon dioxide, oxygen gas, and nitrogen gas?

Back

The atmosphere contains carbon dioxide, oxygen gas, and nitrogen gas.

Front

How does carbon enter the soil?

Back

Carbon enters the soil when decomposers break down carbon from dead organisms, dead plant matter, and waste.

Front

Which sphere of the Earth contains the oceans, ice caps, and glaciers?

Back

The hydrosphere contains the oceans, ice caps, and glaciers.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere of the Earth.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter.

Front

What is cellular respiration?

Back

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

Front

What is decomposition in the context of the carbon cycle?

Back

Decomposition is the process by which dead organisms are broken down by decomposers, returning carbon to the soil and atmosphere.

Front

What is the significance of the atmosphere in the carbon cycle?

Back

The atmosphere is significant in the carbon cycle as it is a major reservoir of carbon dioxide, which is essential for photosynthesis.
