What is the carbon cycle?

Back

The carbon cycle is the movement of carbon through different ecosystems, including processes like photosynthesis, respiration, and decomposition.

What role do phytoplankton play in the carbon cycle?

Back

Phytoplankton use carbon dioxide dissolved in the ocean for photosynthesis, converting it into organic matter.

What is the hydrologic cycle?

Back

The hydrologic cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

What are fossil fuels?

Back

Fossil fuels are carbon-rich geological deposits formed from the remains of dead plants and animals, including coal, oil, and natural gas.

Front

What is the role of clouds in the hydrologic cycle?

Back

Clouds store water in the atmosphere and release it as precipitation.

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.
