Living Things Change

The video discusses how the world is constantly changing and how living things must adapt to survive. It explains the concept of environment and adaptation, using examples like pineapples and polar bears. Historical changes in Earth's environment led to extinctions, affecting the food chain. The peppered moth case study illustrates adaptation to pollution. The video concludes by emphasizing the importance of adaptations in changing environments.

What is the primary difference between an environment and an ecosystem?

• An environment is the same as an ecosystem.

• An environment is a smaller part of an ecosystem.

• An environment refers to non-living conditions, while an ecosystem includes both living and non-living things.

• An environment includes living and non-living things, while an ecosystem only includes living things.

Why did many plants become extinct 360 million years ago?

• They couldn't adapt to the new cool, dry climate.

• They were destroyed by volcanic eruptions.

• They were overrun by new plant species.

• They were eaten by giant insects.

How did the extinction of plants affect giant insects?

• It caused them to migrate to other areas.

• It increased their population.

• It had no effect on them.

• It led to their extinction due to lack of oxygen.

What adaptation helped the dark-colored peppered moths survive during the Industrial Revolution?

• Their dark color that blended with soot-covered trees.

• Their ability to fly faster.

• Their resistance to pollution.

• Their larger size compared to light moths.

What change in the environment led to an increase in the light-colored moth population?

• A rise in temperature.

• An increase in predators.

• A decrease in pollution.

• A change in tree species.
