Carbon - Oxygen Cycle

Front

What is the carbon-oxygen cycle?

Back

The carbon-oxygen cycle is the process by which carbon dioxide and oxygen are exchanged between living organisms and the environment, involving photosynthesis and respiration.

Front

What do plants need to survive that is released by animals?

Back

Carbon dioxide.

Front

What do animals breathe in and release that is used by plants?

Back

Animals breathe in oxygen and release carbon dioxide.

Front

What is respiration in the context of the carbon-oxygen cycle?

Back

Respiration is the process by which animals take in oxygen and release carbon dioxide.

Front

What is photosynthesis?

Back

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

Front

What role do decomposers play in the carbon-oxygen cycle?

Back

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

Front

What do the arrows in a carbon-oxygen cycle diagram represent?

Back

The cycling of carbon dioxide (CO2) and oxygen (O) through the environment.

Front

Why is the carbon-oxygen cycle important for animals?

Back

It provides oxygen, a gas that animals take in when breathing.

Front

What is the main gas that plants absorb during photosynthesis?

Back

Carbon dioxide.

Front

What is the main gas that animals release during respiration?

Back

Carbon dioxide.
