Front

What is deforestation?

Back

The clearing or thinning of forests by humans, which can lead to environmental impacts such as increased carbon dioxide levels.

Front

How does deforestation affect the carbon cycle?

Back

It increases the release of carbon dioxide into the atmosphere, disrupting the natural balance of the carbon cycle.

Front

What role do oceans play in the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and store it, acting as a significant carbon sink.

Front

What is ocean acidification?

Back

The process by which the ocean becomes more acidic due to increased carbon dioxide absorption, affecting marine life.

Front

What are decomposers?

Back

Organisms that break down dead or decaying organisms, returning nutrients to the ecosystem and releasing carbon dioxide.

Front

How do decomposers contribute to the carbon cycle?

Back

By breaking down dead organisms and releasing carbon dioxide back into the atmosphere.

Front

What is the greenhouse effect?

Back

The warming of Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide.

Front

What is the impact of increased carbon dioxide levels on global temperatures?

Back

Increased carbon dioxide levels lead to increased global temperatures, contributing to climate change.

Front

What is a carbon sink?

Back

A natural reservoir that stores carbon-containing chemical compounds for an indefinite period, such as forests and oceans.

Front

What is photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of carbon dioxide and water.
