What is Nitrogen Fixation?

Back

The process of converting nitrogen gas (N2) from the atmosphere into a form that plants and animals can use.

Front

What is the overall purpose of photosynthesis?

Back

To use energy from the sun to produce food (glucose) for the plant.

Front

What gas do plants absorb during photosynthesis?

Back

Carbon dioxide (CO2).

Front

How do animals obtain the nitrogen they need?

Back

From the food they eat.

Front

How is carbon dioxide in the atmosphere changed by living organisms?

Back

It is absorbed by plants during photosynthesis.

Front

What is the role of decomposers in the nitrogen cycle?

Back

Decomposers break down dead organisms, returning nitrogen to the soil.

Front

What is the process by which plants convert sunlight into energy?

Back

Photosynthesis.

Front

What do plants release as a byproduct of photosynthesis?

Back

Oxygen (O2).

Front

What is the significance of the carbon cycle?

Back

It regulates the levels of carbon dioxide in the atmosphere and supports life.
