Carbon Cycle Flashcardizz Quiz

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, and decomposition.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and oxygen to produce energy, releasing carbon dioxide and water as byproducts.

Front

What role do fossil fuels play in the carbon cycle?

Back

Fossil fuels, such as coal, oil, and natural gas, release carbon dioxide into the atmosphere when burned, contributing to the greenhouse effect and climate change.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding the Earth, composed mainly of nitrogen and oxygen, and it plays a crucial role in the carbon cycle.

Front

Why is carbon dioxide considered a greenhouse gas?

Back

Carbon dioxide is considered a greenhouse gas because it absorbs and retains heat from the sun's infrared radiation, contributing to the greenhouse effect.

Front

What is the significance of the greenhouse effect?

Back

The greenhouse effect is essential for maintaining Earth's temperature, but excessive greenhouse gases can lead to global warming and climate change.

Front

How do human activities affect the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, disrupt the carbon cycle by increasing carbon dioxide levels in the atmosphere.

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 role of plants in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to regulate carbon levels and produce oxygen.
