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.

How do animals contribute to the carbon cycle?

Back

Animals eat plants or other animals and breathe out CO2 into the air, contributing to the carbon cycle.

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose (food) and oxygen.

Front

What is cellular respiration?

Back

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

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) than anaerobic respiration, which occurs without oxygen.

Front

What are abiotic factors?

Back

Abiotic factors are non-living components of an ecosystem, such as sunlight, water, temperature, and minerals.

Front

What are biotic factors?

Back

Biotic factors are living or once-living components of an ecosystem, including plants, animals, and microorganisms.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic factors.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organisms, returning nutrients to the soil and releasing carbon back into the atmosphere.

Front

What is the significance of the sun in photosynthesis?

Back

The sun provides the energy needed for photosynthesis, allowing plants to convert carbon dioxide and water into glucose.
