Oxygen Cycle

Front

What is the Oxygen Cycle?

Back

The Oxygen Cycle is the process by which oxygen is exchanged between the atmosphere, living organisms, and the environment. It involves processes like photosynthesis, respiration, and decomposition.

Front

What process do plants use to produce oxygen?

Back

Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is respiration in the context of the oxygen cycle?

Back

Respiration is the process by which living organisms use oxygen to break down glucose for energy, producing carbon dioxide and water as byproducts.

Front

What role do phytoplankton play in the oxygen cycle?

Back

Phytoplankton are tiny plants in the ocean that produce a significant amount of the Earth's oxygen through photosynthesis.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing nutrients back into the ecosystem and using oxygen in the process.

Front

What is combustion?

Back

Combustion is a chemical process that involves burning fuels (like wood or coal) in the presence of oxygen, producing energy, carbon dioxide, and water.

Front

What is oxidation?

Back

Oxidation is a chemical reaction that involves the combination of a substance with oxygen, often resulting in rusting or burning.

Front

How does the oxygen cycle support life on Earth?

Back

The oxygen cycle provides the necessary oxygen for respiration in animals and humans, while also supporting photosynthesis in plants, creating a balance in the ecosystem.

Front

What are the main processes involved in the oxygen cycle?

Back

The main processes are photosynthesis, respiration, decomposition, and combustion.

Front

Why is photosynthesis important for the oxygen cycle?

Back

Photosynthesis is crucial because it produces oxygen, which is essential for the survival of most living organisms.
