What is the Biogeochemical Cycle?

Back

The Biogeochemical Cycle refers to the movement of elements and compounds through living organisms and the physical environment, involving biological, geological, and chemical processes.

Front

What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms, including processes like photosynthesis and respiration.

Front

What role do plants play in the Carbon Cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into glucose and releasing oxygen.

Front

What is respiration in the context of the Carbon Cycle?

Back

Respiration is the process by which animals and plants use oxygen to break down glucose, releasing carbon dioxide back into the atmosphere.

Front

What is the Nitrogen Cycle?

Back

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

Front

Why is nitrogen important for living organisms?

Back

Nitrogen is essential for the production of amino acids, proteins, and nucleic acids, which are vital for all living organisms.

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 role of decomposers in the Biogeochemical Cycle?

Back

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

Front

What is the Phosphorous Cycle?

Back

The Phosphorous Cycle is the movement of phosphorus through the lithosphere, hydrosphere, and biosphere, primarily through the weathering of rocks and uptake by plants.

Front

How does water move through the Water Cycle?

Back

Water moves through the Water Cycle via processes such as evaporation, condensation, precipitation, and infiltration.
