Nitrogen, phosphorous, and sulfur 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 compounds, through biological and physical processes.

Front

How do consumers obtain sulfur?

Back

Consumers obtain sulfur through the food chain, as they eat plants and animals that contain sulfur.

Front

What percentage of the atmosphere is nitrogen gas?

Back

78% of the atmosphere is composed of nitrogen gas.

Front

What is Ammonification?

Back

Ammonification is the process of converting organic nitrogen from dead organisms into ammonia.

Front

What is Denitrification?

Back

Denitrification is the process by which nitrogen compounds are reduced to nitrogen gas, returning it to the atmosphere.

Front

What role do plants play in the Nitrogen Cycle?

Back

Plants absorb nitrogen from the soil in the form of nitrates and use it to synthesize proteins and nucleic acids.

Front

What is Nitrogen Fixation?

Back

Nitrogen Fixation is the process of converting nitrogen gas from the atmosphere into ammonia, which can be used by plants.

Front

What are decomposers?

Back

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

Front

What is the role of bacteria in the Nitrogen Cycle?

Back

Bacteria play crucial roles in the Nitrogen Cycle, including nitrogen fixation, ammonification, and nitrification.

Front

What is the significance of the Phosphorus Cycle?

Back

The Phosphorus Cycle is important for the growth of plants and animals, as phosphorus is a key component of DNA, RNA, and ATP.
