Impact of Oil Spills on Ecosystems

The video explores ecosystems, focusing on the impact of human activities like oil spills. It simulates an oil spill, discusses cleanup methods, and highlights the importance of preventing such incidents to maintain ecosystem balance.

What is a sustainable ecosystem?

• An ecosystem that can support a variety of living things over a long period.

• An ecosystem that is constantly changing.

• An ecosystem with no abiotic factors.

• An ecosystem that only supports plant life.

What is the carrying capacity of an ecosystem?

• The number of abiotic factors in an ecosystem.

• The minimum number of species needed for an ecosystem.

• The maximum number of species an ecosystem can support.

• The average number of species in an ecosystem.

Which of the following is a human activity that impacts ecosystems?

• Volcanic eruptions

What is a common characteristic of oil in water?

• Oil is denser than water.

Which method involves burning oil off the water's surface?

• In-situ burning

• Skimmers

• Booms

• Dispersants

What is the role of dispersants in oil spill cleanup?

• They physically remove oil from water.

• They burn oil off the water's surface.

• They help oil and water mix more readily.

• They prevent oil from reaching the shore.

How do oil spills affect seabirds?

• They have no effect on seabirds.

• They clump feathers, preventing flight and warmth.

• They help seabirds fly better.

• They provide additional food for seabirds.

What is a keystone species?

• A species that is always at the top of the food chain.

• A species that has no impact on its ecosystem.

• A species that affects the entire ecosystem's health.

• A species that is the most numerous in an ecosystem.

Why is preventing oil spills important?

• To preserve biodiversity and food webs.

• To increase oil production.

• Because oil spills have no long-term effects.

• Because cleanup is easy and quick.

What is one way to reduce the risk of oil spills?

• Use more plastic products.

• Drive less and reduce plastic use.

• Build more oil pipelines.

• Increase oil extraction.
