What is the ozone layer?

Back

The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O3) molecules, which absorb most of the sun's harmful ultraviolet (UV) radiation.

What are the effects of ozone layer depletion?

Back

Depletion of the ozone layer can lead to increased UV radiation reaching the Earth's surface, resulting in higher rates of skin cancer, cataracts, and harm to ecosystems.

Front

What are the three main types of biodiversity?

The three main types of biodiversity are species diversity, genetic diversity, and ecosystem diversity.

Front

What is biomagnification?

Back

Biomagnification is the process by which the concentration of toxins increases in organisms at each successive level of the food chain.

Front

What is the impact of overfishing on ecosystems?

Back

Overfishing can lead to the depletion of fish populations, disrupting food chains and causing severe damage to marine ecosystems.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.
