Carbon Cycle

Front

What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, such as plants and animals, that have been buried and subjected to heat and pressure over millions of years. Examples include coal, oil, and natural gas.

Front

What role does photosynthesis play in the Carbon Cycle?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide from the atmosphere into glucose and oxygen. It removes carbon dioxide from the atmosphere.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It releases carbon dioxide back into the atmosphere.

Front

How do humans contribute to the Carbon Cycle?

Back

Humans contribute to the Carbon Cycle primarily through activities like burning fossil fuels for energy, which releases carbon dioxide into the atmosphere, and deforestation, which reduces the number of trees that can absorb carbon dioxide.

Front

What is the significance of decomposers in the Carbon Cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere. They play a crucial role in recycling nutrients and maintaining the balance of the Carbon Cycle.

Front

What happens to carbon when fossil fuels are burned?

Back

When fossil fuels are burned, carbon that was stored in these fuels is released into the atmosphere as carbon dioxide, contributing to greenhouse gas emissions.

Front

What is the relationship between respiration and the Carbon Cycle?

Back

Respiration is a process that releases carbon dioxide into the atmosphere as organisms convert glucose and oxygen into energy. It is a key part of the Carbon Cycle.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen. Plants use sunlight to convert carbon dioxide and water into these substances.

Front

What is the role of trees in the Carbon Cycle?

Back

Trees absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce greenhouse gases and providing oxygen as a byproduct.
