The 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 role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, using it to produce oxygen and glucose, which are essential for their growth.

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle by exhaling carbon dioxide during respiration, which returns carbon to the atmosphere.

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, increasing greenhouse gas concentrations and contributing to climate change.

What is deforestation and how does it affect the carbon cycle?

Back

Deforestation is the clearing of forests, which reduces the number of trees that can absorb carbon dioxide, leading to higher levels of CO2 in the atmosphere.

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide, methane, and water vapor.

What is photosynthesis?

Back

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

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 back into the atmosphere.

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, largely driven by increased levels of greenhouse gases.

What is carbon footprint?

Back

A carbon footprint is the total amount of greenhouse gases emitted directly or indirectly by an individual, organization, event, or product, usually measured in carbon dioxide equivalents.
