Carbon Cycle Review

Front

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.

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis removes carbon dioxide from the atmosphere as plants convert it into glucose using sunlight.

Front

How do humans obtain carbon?

Back

Humans obtain carbon by consuming plants and animals, which are part of the carbon cycle.

Front

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

Back

Burning fossil fuels releases carbon dioxide into the atmosphere faster than it can be absorbed, contributing to global warming.

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

Front

What role do trees play in the carbon cycle?

Back

Trees absorb carbon dioxide during photosynthesis, helping to reduce the amount of CO2 in the atmosphere.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.

Front

What is decomposition in the context of the carbon cycle?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing carbon back into the atmosphere as carbon dioxide.

Front

How does deforestation affect the carbon cycle?

Back

Deforestation reduces the number of trees available to absorb carbon dioxide, leading to increased levels of CO2 in the atmosphere.

Front

What is a greenhouse gas?

Back

A greenhouse gas is a gas that traps heat in the atmosphere, contributing to the greenhouse effect. Carbon dioxide is one of the most significant greenhouse gases.
