Carbon Cycle

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.

What do plants use to make their own food?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose (food) and oxygen.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance (usually a fuel) reacts with oxygen to produce heat and light, commonly referred to as burning.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, which is essential for nutrient cycling.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily composed of carbon, and are used as energy sources.

Front

How does respiration contribute to the carbon cycle?

Back

During respiration, living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, playing a crucial role in regulating Earth's temperature.

Front

What human activities increase carbon dioxide levels in the atmosphere?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes increase carbon dioxide levels in the atmosphere.

Front

What is the impact of deforestation on the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to higher levels of carbon in the atmosphere.
