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 fossilization.

How do living organisms return carbon to the atmosphere?

Back

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

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 role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into glucose and oxygen.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are oxygen and glucose.

Front

What happens to organisms that do not decompose?

Back

Organisms that do not decompose can be buried and eventually become fossil fuels.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning carbon to the soil and atmosphere.

Front

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels are significant because they store carbon that was once part of living organisms, and when burned, they release carbon dioxide back into the atmosphere.

Front

How does carbon dioxide contribute to climate change?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to global warming and climate change.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis and respiration are complementary processes; photosynthesis removes carbon dioxide from the atmosphere, while respiration releases it.
