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.

What process do plants use to produce oxygen?

Back

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

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

What is combustion?

Back

Combustion is a chemical process in which a substance reacts rapidly with oxygen, producing heat and light, commonly seen in burning fuels.

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 respiration?

Back

Respiration is the process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide and water as byproducts.

Front

How does sunlight contribute to the oxygen cycle?

Back

Sunlight is essential for photosynthesis, allowing plants to produce oxygen, which is then released into the atmosphere.

Front

What is the significance of decomposing in the oxygen cycle?

Back

Decomposition is the process by which dead organic matter is broken down, releasing nutrients back into the soil and carbon dioxide into the atmosphere.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis produces oxygen and glucose, while respiration uses oxygen to release energy from glucose, creating a cycle of oxygen and carbon dioxide.

Front

What are the main components of the oxygen cycle?

Back

The main components of the oxygen cycle include photosynthesis, respiration, decomposition, and combustion.
