3 Carbon Cycle

Front

What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon is exchanged between the Earth's atmosphere, land, water, and living organisms. It involves various processes such as photosynthesis, respiration, and decomposition.

Front

How does carbon dioxide EXIT the atmosphere?

Back

Carbon dioxide exits the atmosphere primarily through photosynthesis, where plants convert CO2 into glucose.

Front

How does carbon ENTER the atmosphere?

Back

Carbon enters the atmosphere mainly through respiration, where living organisms release CO2 as a byproduct of energy production.

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 carbon dioxide and water, producing oxygen as a byproduct.

Front

What is respiration?

Back

Respiration is the biochemical process in which living organisms convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

Where are organic compounds like glucose found?

Back

Organic compounds like glucose (C6H12O6) are primarily found in the biosphere, within living organisms.

Front

What is the role of the ocean in the carbon cycle?

Back

The ocean acts as a major carbon reservoir, storing carbon in the form of dissolved carbon dioxide and carbonic acid.

Front

What is carbonic acid?

Back

Carbonic acid (H2CO3) is a weak acid formed when carbon dioxide dissolves in water, playing a crucial role in the carbon cycle.

Front

What is the geosphere?

Back

The geosphere refers to the solid parts of the Earth, including rocks, soil, and sediments, which store carbon in various forms.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where living organisms interact with each other and their environment, playing a key role in the carbon cycle.
