Carbon - Oxygen Cycle

Front

What is the carbon-oxygen cycle?

Back

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

Front

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

Back

Carbon dioxide.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms that have been buried and subjected to heat and pressure over millions of years.

Front

What is photosynthesis?

Back

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

Front

What do plants absorb during photosynthesis?

Back

Carbon dioxide (CO2).

Front

What is the role of respiration in the carbon cycle?

Back

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

Front

How do fossil fuels affect the carbon cycle when burned?

Back

Burning fossil fuels adds carbon dioxide to the atmosphere.

Front

What is the primary source of energy for photosynthesis?

Back

Energy from the Sun.

Front

What happens to carbon dioxide in the soil?

Back

It can be used by decomposers or absorbed by plants during photosynthesis.

Front

What is the significance of decomposers in the carbon cycle?

Back

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