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 such as photosynthesis, respiration, decomposition, and combustion.

How does carpooling and public transportation affect atmospheric carbon dioxide levels?

Back

Carpooling and public transportation decrease the amount of atmospheric carbon dioxide by reducing the number of vehicles on the road, leading to lower fossil fuel consumption.

Front

What impact do industrial activities have on atmospheric carbon dioxide?

Back

Industrial activities increase the amount of atmospheric carbon dioxide due to the burning of fossil fuels and other processes that release carbon into the atmosphere.

Front

What are nonrenewable resources?

Back

Nonrenewable resources are natural resources that cannot be replenished within a human timescale, such as petroleum and coal, which are finite and will eventually be depleted.

Front

How do recycling and reusing materials affect carbon dioxide levels?

Back

Recycling and reusing materials decrease the amount of atmospheric carbon dioxide by reducing the need for new production processes that typically emit carbon.

Front

What role do plants play in the carbon cycle?

Back

Plants play a crucial role in the carbon cycle by absorbing carbon dioxide from the atmosphere during photosynthesis and releasing oxygen.

Front

What is photosynthesis?

Back

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

Front

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.

Front

What is the significance of decomposition in the carbon cycle?

Back

Decomposition is significant in the carbon cycle as it breaks down dead organic matter, returning carbon to the soil and atmosphere, thus maintaining the cycle.

Front

How does combustion affect the carbon cycle?

Back

Combustion, such as burning fossil fuels, releases stored carbon into the atmosphere as carbon dioxide, contributing to climate change.
