Carbon Cycle Exam Review

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 like 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 it into glucose and oxygen.

Front

What do plants release that is essential for human survival?

Back

Plants release oxygen, which is essential for human survival.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis converts carbon dioxide and sunlight into glucose and oxygen, thus playing a crucial role in removing carbon from the atmosphere.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, which have been buried and transformed over millions of years. They include coal, oil, and natural gas.

Front

How do burning fossil fuels affect the carbon cycle?

Back

Burning fossil fuels releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change.

Front

What is decomposition in the carbon cycle?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing carbon back into the soil and atmosphere.

Front

What is the significance of carbon sinks?

Back

Carbon sinks are natural systems, like forests and oceans, that absorb more carbon than they release, helping to mitigate climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide, in the atmosphere.
