Nitrogen Cycle

Front

What is the Nitrogen Cycle?

Back

The Nitrogen Cycle is the process by which nitrogen is converted between its various chemical forms, including nitrogen gas, ammonia, nitrates, and organic nitrogen, in the environment.

Front

What role do bacteria play in the Nitrogen Cycle?

Back

Bacteria convert nitrogen gas from the atmosphere into a usable form for plants and animals through a process called nitrogen fixation.

Front

Why do organisms need nitrogen?

Back

Organisms need nitrogen to build proteins and DNA, which are essential for growth and reproduction.

Front

What is an Algae Bloom?

Back

An Algae Bloom is a rapid increase in the population of algae in water bodies, often caused by excess nitrogen and phosphorus, leading to negative environmental impacts.

Front

What is Denitrification?

Back

Denitrification is the process by which bacteria convert nitrates back into nitrogen gas, releasing it into the atmosphere and completing the nitrogen cycle.

Front

What are Decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead plant and animal matter, returning nutrients, including nitrogen, to the soil.

Front

What is Nitrogen Fixation?

Back

Nitrogen Fixation is the process of converting nitrogen gas from the atmosphere into ammonia or related compounds in soil, making it available for plants.

Front

What happens during Ammonification?

Back

Ammonification is the process where decomposers break down organic matter, releasing ammonia into the soil.

Front

What is the impact of excess nitrogen in oceans?

Back

Excess nitrogen in oceans can lead to Algae Blooms, which deplete oxygen in the water and harm marine life.

Front

What is the difference between Nitrogen Fixation and Denitrification?

Back

Nitrogen Fixation converts nitrogen gas into a usable form for plants, while Denitrification converts nitrates back into nitrogen gas, releasing it into the atmosphere.
