Carbon & Nitrogen Cycles

Front

What does fixation mean in terms of the carbon and nitrogen cycles?

Back

Fixation refers to changing carbon or nitrogen into a form that is usable by living things.

Front

What human activity negatively affects the nitrogen cycle?

Back

Overusing fertilizers negatively affects the nitrogen cycle.

Front

Which type of organism fixes carbon?

Back

Producers are the organisms that fix carbon.

Front

Which process removes carbon dioxide from the atmosphere?

Back

Photosynthesis removes carbon dioxide from the atmosphere.

Front

What would happen if bacteria were removed from this ecosystem?

Back

Nitrogen would not be available in a form that plants and animals can use.

Front

What is the role of producers in the carbon cycle?

Back

Producers convert carbon dioxide into organic matter through photosynthesis.

Front

How does decomposition contribute to the nitrogen cycle?

Back

Decomposition recycles nutrients back into the soil, making nitrogen available for plants.

Front

What is denitrification?

Back

Denitrification is the process by which nitrogen gas is released back into the atmosphere by bacteria.

Front

What is the significance of nitrogen-fixing bacteria?

Back

Nitrogen-fixing bacteria convert atmospheric nitrogen into forms that plants can absorb and use.

Front

How do human activities like deforestation impact the carbon cycle?

Back

Deforestation increases carbon dioxide levels in the atmosphere by reducing the number of trees that can absorb it.
