The Nitrogen Cycle For Kids
The Nitrogen cycle for kids is set and designed to test and advance the basic knowledge on the Nitrogen part of the air. Beginners are advised to take it up and understand the simple facts and concepts about Nitrogen.

What happens to Nitrogen after a cow excretes it?
- A.
The cow explodes
- B.
Forms soil
- C.
Decomposes
- D.
Nitrifies Bacteria
Correct Answer
C. DecomposesExplanation
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.Rate this question:

What does nitrifying bacteria convert ammonia to?
- A.
Nitrites
- B.
Nitrates
- C.
Doug's hair
- D.
Poison Gas
- E.
Nitrudes
Correct Answer
B. NitratesExplanation
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.Rate this question:

What does denitrifying bacteria do to Nitrogen?
- A.
Turns Hamish's hair pink
- B.
The Correct Answer
- C.
The Wrong answer
- D.
Releases it into the air
- E.
It joins with a Carbon Atom
- F.
You should have selected the Correct Answer
Correct Answer
D. Releases it into the airExplanation
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.Rate this question:

What do nitrates do to animals after they are eaten by them?
- A.
Builds animal proteins
- B.
Builds muscle content
- C.
Builds animal fat
- D.
Builds proteins
Correct Answer
A. Builds animal proteinsExplanation
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.Rate this question:
