What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including nitrogen fixation, nitrification, assimilation, ammonification, and denitrification.

Front

What is assimilation in the nitrogen cycle?

Back

Assimilation is the process by which plants and animals incorporate nitrogen from organic compounds into their own tissues.

Front

Define urban areas.

Back

Urban areas are regions characterized by high population density and vast human-built features in comparison to areas surrounding them.

Front

What is nitrification?

Back

Nitrification is the biological process by which ammonia is converted into nitrites and then into nitrates by bacteria.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria are essential in the nitrogen cycle as they perform processes like nitrogen fixation, nitrification, and ammonification.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both organisms benefit from the interaction.

Front

How does nitrogen fixation occur?

Back

Nitrogen fixation occurs through the action of certain bacteria and through natural phenomena like lightning, converting atmospheric nitrogen into a usable form for plants.

Front

What is denitrification?

Back

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

Front

Explain the term 'ammonification'.

Back

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

Front

What is the significance of the nitrogen cycle in ecosystems?

Back

The nitrogen cycle is crucial for ecosystems as it recycles nitrogen, an essential nutrient for plant growth, thus supporting food chains.
