Back

The phosphorus cycle is the process by which phosphorus moves through the environment, including soil, water, and living organisms, and is essential for plant growth.

Front

How do humans decrease phosphorus in the environment?

Back

Deforestation: cutting down trees.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process where bacteria and lightning convert nitrogen gas (N2) from the atmosphere into ammonia, which can be used by plants.

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, including processes like evaporation, condensation, and precipitation.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, playing a crucial role in regulating Earth's climate.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter.

Front

What is deforestation?

Back

Deforestation is the clearing or thinning of forests by humans, which can lead to increased carbon dioxide levels in the atmosphere.
