The Nitrogen Cycle For Kids

1. What does denitrifying bacteria do to Nitrogen?

The Correct Answer

The Wrong answer

Releases it into the air

It joins with a Carbon Atom

You should have selected the Correct Answer

Denitrifying bacteria release nitrogen into the air. Denitrification is the process by which these bacteria convert nitrates (NO3-) into nitrogen gas (N2), which is then released into the atmosphere. This process helps to balance the nitrogen cycle by removing excess nitrogen from ecosystems.

2. What happens to Nitrogen after a cow excretes it?

The cow explodes

Forms soil

Decomposes

Nitrifies Bacteria

After a cow excretes nitrogen, it undergoes decomposition. Decomposition refers to the breakdown of organic matter by microorganisms, such as bacteria and fungi. In the case of nitrogen, it is broken down into simpler compounds, such as ammonia and nitrate, through the activity of decomposer organisms. This process is essential for returning nitrogen back into the environment and making it available for other organisms to use.

3. What does nitrifying bacteria convert ammonia to?

Nitrites

Nitrates

Poison Gas

Nitrudes

Nitrifying bacteria convert ammonia to nitrates. This process, known as nitrification, involves two types of bacteria: ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB). AOB convert ammonia to nitrites, and then NOB further convert nitrites to nitrates. Nitrates are an essential form of nitrogen that can be taken up by plants for growth. This conversion is an important step in the nitrogen cycle, ensuring that ammonia produced from organic matter decomposition is converted into a usable form by plants and other organisms.

4. True or False- do Nitrogen fixing bacteria nitrogen from the atmosphere into nitrites?

True

False

It turns into nitrates.

Explanation

It turns into nitrates.

5. What do nitrates do to animals after they are eaten by them?

Builds animal proteins

Builds muscle content

Builds animal fat

Builds proteins

Nitrates, when consumed by animals, contribute to the building of animal proteins. Proteins are essential for various biological processes, including the growth and repair of tissues, enzyme production, and hormone regulation. Nitrates provide the necessary nitrogen for the synthesis of amino acids, the building blocks of proteins. Therefore, the consumption of nitrates helps animals in the formation and maintenance of their protein content, which is crucial for their overall health and development.
