B-LS2-5 Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon atoms are recycled through the Earth's ecosystems, including the atmosphere, oceans, soil, and living organisms.

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 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 as a byproduct.

Front

What are carbon reservoirs?

Back

Carbon reservoirs are natural systems that store carbon, such as forests, oceans, and soil.

Front

What is the effect of fossil fuel combustion on the carbon cycle?

Back

Combustion of fossil fuels adds carbon dioxide to the atmosphere, contributing to climate change.

Front

What is the equation for photosynthesis?

Back

CO₂ + light + H₂O → O₂ + Sugar

Front

How does deforestation affect the carbon cycle?

Back

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

Front

What role do oceans play in the carbon cycle?

Back

Oceans act as a major carbon sink, absorbing carbon dioxide from the atmosphere and storing it in water and marine organisms.

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 dioxide back into the atmosphere.

Front

What is the impact of increased marine biota on the carbon cycle?

Back

Increased marine biota can enhance carbon sequestration in oceans, helping to reduce atmospheric carbon dioxide levels.
