What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What effect do fossil fuels have on the carbon cycle?

Back

Burning fossil fuels adds carbon dioxide to the atmosphere, which can contribute to climate change.

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, producing carbon dioxide and water as byproducts.

Front

What is combustion?

Back

Combustion is a chemical process in which a substance reacts rapidly with oxygen, producing heat and light, and often resulting in the release of carbon dioxide.

Front

How do plants remove carbon from the atmosphere?

Back

Plants remove carbon from the atmosphere through the process of photosynthesis, where they convert carbon dioxide into glucose.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the key reactants in photosynthesis, where it is used by plants to produce glucose.

Front

What is the relationship between respiration and photosynthesis?

Back

Respiration and photosynthesis are interconnected processes; photosynthesis produces oxygen and glucose, which are used in respiration to release energy.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of carbon, and include coal, oil, and natural gas.

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, involving processes like photosynthesis, respiration, and combustion.

Front

What is bioremediation?

Back

Bioremediation is the use of living organisms, often microbes, to remove or neutralize contaminants from soil and water.
