Carbon Cycle

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. It involves processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process that removes carbon dioxide from the atmosphere, as plants convert CO2 into glucose using sunlight.

Front

Which processes release carbon dioxide into the atmosphere?

Back

Processes that release carbon dioxide include burning fossil fuels, respiration in animals and plants, and volcanic eruptions.

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, producing carbon dioxide and water as byproducts.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon back into the atmosphere as carbon dioxide during the decomposition process.

Front

What is subduction?

Back

Subduction is a geological process where one tectonic plate moves under another plate and sinks into the mantle, which can release carbon stored in rocks back into the atmosphere.

Front

How do volcanoes contribute to the carbon cycle?

Back

Volcanoes release carbon dioxide into the atmosphere during eruptions, contributing to the natural carbon cycle.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, significantly increasing greenhouse gas concentrations and contributing to climate change.

Front

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

Back

The ocean acts as a major carbon sink, absorbing carbon dioxide from the atmosphere and storing it in water and marine organisms.
