What is deforestation?

Back

Deforestation is the process of clearing forests by cutting down trees.

Front

How does deforestation affect ecosystems?

Back

Deforestation disrupts the balance of oxygen and carbon dioxide, reduces biodiversity, causes soil erosion, and impacts the water cycle.

Front

What are some examples of pollution in ecosystems? Options: Air pollution, water pollution, soil pollution, noise pollution, Land pollution, Thermal pollution, Light pollution

Back

Air pollution, water pollution, soil pollution, noise pollution

Front

Explain the impact of pollution on aquatic ecosystems.

Back

Pollution impacts aquatic ecosystems by decreasing water quality, harming aquatic life, disrupting the ecosystem balance, reducing biodiversity, and potentially causing species extinction.

Front

What is overfishing and why is it harmful?

Back

Overfishing is harmful because it depletes fish populations, disrupts marine ecosystems, leads to loss of biodiversity, and negatively impacts the food chain.

Front

How does overfishing disrupt marine food chains?

Back

Overfishing depletes key species, leading to imbalances in the ecosystem.

Front

What are the main causes of climate change? Options: Deforestation, Solar activity, Volcanic eruptions, Greenhouse gas emissions from human activities

Back

Greenhouse gas emissions from human activities

Front

Describe the effects of climate change on ecosystems.

Back

Climate change can disrupt ecosystems by altering temperature, precipitation patterns, and sea levels. This can lead to habitat loss, species extinction, changes in migration patterns, and disruptions in food chains.

Front

What are invasive species and how do they impact ecosystems?

Back

Invasive species are non-native organisms that cause harm to the ecosystem they invade by outcompeting native species, disrupting food chains, altering habitats, and spreading diseases.

Front

Provide an example of an invasive species and its effects on a specific ecosystem.
