Carbon - Oxygen Cycle

Front

What is the carbon-oxygen cycle?

Back

The carbon-oxygen cycle is the process by which carbon dioxide is used by plants during photosynthesis to produce oxygen, which is then used by animals for respiration, releasing carbon dioxide back into the atmosphere.

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 photosynthesis?

Back

Photosynthesis is the process by which plants absorb carbon dioxide from the atmosphere and convert it into glucose and oxygen using sunlight.

Front

What is respiration?

Back

Respiration is the process by which animals and plants convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.

Front

What role do decomposers play in the carbon cycle?

Back

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

Front

Is all carbon in existence continually recycled?

Back

True.

Front

What happens during the process of respiration?

Back

During respiration, organisms take in oxygen and release carbon dioxide.

Front

What is the significance of the carbon-oxygen cycle for life on Earth?

Back

The carbon-oxygen cycle is essential for maintaining the balance of oxygen and carbon dioxide in the atmosphere, supporting life.

Front

How do human activities affect the carbon-oxygen cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, disrupting the natural carbon-oxygen cycle.
