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 process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process that removes carbon dioxide from the atmosphere, as plants convert CO2 into glucose and oxygen.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen to produce heat and light, commonly referred to as burning.

Front

What are fossil fuels?

Back

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

Front

Where is glucose (C6H12O6) primarily found?

Back

Glucose is primarily found in plants, where it is produced during photosynthesis, but it is also present in animals as a source of energy.

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 and water as byproducts.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus playing a crucial role in recycling nutrients.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to the greenhouse effect and climate change.

Front

How do human activities impact the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis and respiration are complementary processes; photosynthesis removes CO2 from the atmosphere, while respiration releases it back.
