What is denitrification?

Back

The conversion of nitrite back to nitrogen gas.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria help in nitrogen fixation and denitrification processes.

Front

What is the importance of the carbon cycle?

Back

It regulates the Earth's climate and supports life by cycling carbon through ecosystems.

Front

What is the role of decomposers in the nitrogen cycle?

Back

Decomposers break down organic matter, releasing nitrogen back into the soil.

Front

What is the primary source of nitrogen in the atmosphere?

Back

Nitrogen gas (N2) makes up about 78% of the Earth's atmosphere.
