Biogeochemical Cycles

Front

What are biogeochemical cycles?

Back

Biogeochemical cycles are natural processes that recycle nutrients in various chemical forms from the environment to organisms and then back to the environment.

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, decomposition, and combustion.

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 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 cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is decomposition?

Back

Decomposition is the process by which organic substances are broken down into simpler organic or inorganic matter, releasing nutrients back into the environment.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, including coal, oil, and natural gas, and are used as energy sources.

Front

How do volcanoes affect the carbon cycle?

Back

Volcanoes release carbon dioxide into the atmosphere, increasing the levels of CO2 and contributing to the greenhouse effect.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, which can be accessed by plant roots and wells.

Front

What is the role of carbon-fixing bacteria?

Back

Carbon-fixing bacteria convert carbon dioxide into organic compounds, playing a crucial role in the carbon cycle, especially in anaerobic environments.
