Environmental Impact and Ecosystem Dynamics

The video explores the human impact on ecosystems, focusing on how activities like urbanization, pollution, and resource extraction disrupt food webs and habitats. It discusses specific issues such as light pollution, global warming, and deforestation, highlighting their effects on biodiversity and ecosystem balance. The video also covers the consequences of peat bog destruction, plastic pollution, and overfishing, emphasizing the need for sustainable practices to mitigate these impacts.

What happens to the population of rats if all the frogs in an ecosystem die?

• The rat population becomes extinct.

• The rat population remains the same.

• The rat population decreases.

• The rat population increases.

How does the growing human population affect the environment?

• It reduces the need for raw materials.

• It decreases energy consumption.

• It increases the strain on resources.

• It leads to less waste production.

What is one effect of light pollution on animals?

• It has no effect on animal behavior.

• It confuses baby sea turtles.

• It increases the number of predators.

• It helps prey hide from predators.

What is a consequence of impermeable surfaces in cities?

• More plant growth

• Increased flooding

• Less air pollution

• Improved water drainage

What causes global dimming?

• Increased sunlight

• Burning fossil fuels

• Rising sea levels

• Deforestation

How does global warming affect weather patterns?

• It reduces rainfall.

• It has no effect on weather.

• It causes extreme weather patterns.

• It stabilizes weather patterns.

What is a significant risk of peat bog destruction?

• Increased oxygen levels

• Release of carbon dioxide

• Decreased soil nutrients

• More plant diversity

What is a major problem caused by plastics in the ocean?

• They decompose quickly.

• They provide nutrients for marine life.

• They harm marine animals.

• They improve water quality.

How does deforestation impact ecosystems?

• It creates new habitats.

• It stabilizes food chains.

• It increases biodiversity.

• It destroys ecosystems.

What is a consequence of overfishing?

• Improved aquatic habitats

• Disruption of food chains

• More nutrients in the ecosystem

• Increased fish populations
