Nutrient Cycles

Front

What is the Nitrogen Cycle?

Back

The Nitrogen Cycle is the process by which nitrogen is converted between its various chemical forms, including atmospheric nitrogen, organic nitrogen, and inorganic nitrogen compounds, allowing it to be used by living organisms.

Front

What role do bacteria play in the Nitrogen Cycle?

Back

Bacteria in the soil convert atmospheric nitrogen into ammonia, which can then be used by plants.

Front

What is the Carbon Cycle?

Back

The Carbon Cycle is the series of processes by which carbon compounds are interconverted in the environment, including photosynthesis, respiration, and decomposition.

Front

How do plants obtain nitrogen?

Back

Plants obtain nitrogen through the uptake of nitrogen compounds from the soil, such as nitrates and ammonium.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the Water Cycle?

Back

The Water Cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes such as evaporation, condensation, precipitation, and infiltration.

Front

What is the role of decomposers in nutrient cycles?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for plants.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as vapor through pores in leaves.

Front

What is the significance of the Phosphorous Cycle?

Back

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

Front

How does carbon dioxide enter the atmosphere?

Back

Carbon dioxide enters the atmosphere through processes such as respiration, combustion of fossil fuels, and decomposition.
