Front

What is nitrogen fixation?

Back

The process of converting nitrogen gas from the atmosphere into a form that plants can use, primarily through bacteria or lightning.

Front

Name two ways nitrogen fixation occurs.

Back

1. Lightning 2. Bacteria

Front

What is the role of decomposition in the nitrogen cycle?

Back

Decomposition returns nitrogen to the soil and atmosphere by breaking down dead organisms and waste.

Front

What do plants use nitrogen for?

Back

Plants use nitrogen to make proteins, which are essential for growth and development.

Front

What is the carbon cycle?

Back

The process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into glucose.

Front

What is combustion in the context of the carbon cycle?

Back

Combustion is the process of burning fossil fuels, which releases carbon dioxide back into the atmosphere.

Front

What role do animals play in the carbon cycle?

Back

Animals release carbon dioxide into the atmosphere through respiration.

Front

What is the significance of photosynthesis in the carbon cycle?

Back

Photosynthesis is crucial as it removes carbon dioxide from the atmosphere and produces oxygen.

Front

What is the role of bacteria in the nitrogen cycle?

Back

Bacteria help in nitrogen fixation and decomposition, making nitrogen available to plants.
