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, and decomposition.

Front

What is the Nitrogen Cycle?

Back

The Nitrogen Cycle is the process through which nitrogen is converted between its various chemical forms, including nitrogen fixation, nitrification, denitrification, and ammonification.

Front

How do plants absorb carbon dioxide?

Back

Plants absorb carbon dioxide from the atmosphere through small openings in their leaves called stomata during the process of photosynthesis.

Front

What role do bacteria play in the Nitrogen Cycle?

Back

Bacteria play crucial roles in the Nitrogen Cycle by fixing nitrogen from the atmosphere, converting it into forms usable by plants, and denitrifying nitrates back into nitrogen gas.

Front

What is photosynthesis?

Back

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

Front

What is denitrification?

Back

Denitrification is the process by which denitrifying bacteria convert nitrates in the soil back into nitrogen gas, releasing it into the atmosphere.

Front

What is the significance of greenhouse gases?

Back

Greenhouse gases, such as carbon dioxide and water vapor, trap heat in the atmosphere, contributing to the greenhouse effect and global warming.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process of converting nitrogen gas from the atmosphere into ammonia or related compounds in the soil, making it available for plant uptake.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases carbon dioxide into the atmosphere, increasing greenhouse gas concentrations and contributing to climate change.
