Carbon & Nitrogen Cycles

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. It involves processes like photosynthesis, respiration, decomposition, and combustion.

Front

What is Photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is Cellular Respiration?

Back

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

Front

What role do plants play in the Carbon Cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce greenhouse gases and provide oxygen.

Front

What is Nitrogen Fixation?

Back

Nitrogen Fixation is the process by which nitrogen gas from the atmosphere is converted into ammonia or related compounds in soil, making nitrogen available to plants.

Front

How do animals obtain nitrogen?

Back

Animals obtain nitrogen by consuming plants or other animals that have absorbed nitrogen from the soil.

Front

What is a Greenhouse Gas?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide, methane, and water vapor.

Front

What is the significance of the ocean in the Carbon Cycle?

Back

The ocean absorbs carbon dioxide from the atmosphere and plays a crucial role in regulating global climate and supporting marine life through photosynthesis.

Front

What is Decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning nutrients, including carbon, back to the soil.

Front

What is the role of water vapor in the atmosphere?

Back

Water vapor is a greenhouse gas that helps to regulate the Earth's temperature by trapping heat in the atmosphere.
