Carbon Cycle

Front

What do plants use to make their own food?

Back

Plants use water, sunlight, and carbon dioxide to make their own food through the process of photosynthesis.

Front

What is respiration in animals?

Back

Respiration is the process by which animals take in oxygen and release carbon dioxide.

Front

Which process removes carbon from the atmosphere?

Back

Photosynthesis removes carbon from the atmosphere.

Front

What happens when humans burn fossil fuels?

Back

When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.

Front

What can organisms that do not decompose become?

Back

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

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of carbon dioxide in the carbon cycle?

Back

Carbon dioxide is used by plants during photosynthesis to produce oxygen and glucose.

Front

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

Back

Fossil fuels store carbon that was once part of living organisms and release it back into the atmosphere when burned.

Front

Explain the process of decomposition.

Back

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

Front

What is the relationship between respiration and photosynthesis?

Back

Respiration and photosynthesis are interconnected processes; photosynthesis produces oxygen and glucose, which are used in respiration to release energy.
