Carbon Cycle: How Carbon Moves through the Systems?

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 various processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What process do plants use to convert carbon dioxide into glucose?

Back

Photosynthesis.

Front

What is cellular respiration?

Back

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

Front

How does deforestation affect atmospheric carbon dioxide levels?

Back

Deforestation increases the amount of atmospheric carbon dioxide by reducing the number of trees that can absorb CO2 through photosynthesis.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon back into the atmosphere as carbon dioxide.

Front

What is combustion?

Back

Combustion is a chemical process in which a substance reacts with oxygen to produce heat and light, commonly referred to as burning.

Front

Which process removes carbon from the atmosphere?

Back

Photosynthesis removes carbon from the atmosphere.

Front

True or False: All carbon in existence is continually recycled in the carbon cycle.

Back

True.

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

What is the significance of carbon sinks?

Back

Carbon sinks are natural systems, such as forests and oceans, that absorb more carbon than they release, helping to mitigate climate change.
