EOC Review: Carbon Cycle

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of coal, oil, and natural gas.

Front

Which process removes carbon from the atmosphere?

Back

Photosynthesis is the process by which plants convert carbon dioxide from the atmosphere into glucose and oxygen.

Front

What are the two main processes that fuel the carbon cycle?

Back

The two main processes are respiration and photosynthesis.

Front

How do living organisms return carbon back into the atmosphere?

Back

Living organisms return carbon to the atmosphere through decomposition and respiration.

Front

What process does NOT produce carbon dioxide?

Back

Photosynthesis does not produce carbon dioxide; it consumes it.

Front

What is the role of decomposition in the carbon cycle?

Back

Decomposition breaks down dead organic matter, releasing carbon back into the atmosphere as carbon dioxide.

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 as a byproduct.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate, supporting life, and maintaining the balance of carbon in the atmosphere.

Front

What are the main sources of carbon dioxide emissions?

Back

Main sources include burning fossil fuels, deforestation, and industrial processes.
