Survival and Adaptation in Ecosystems

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 animals. Historical changes in the Earth's environment led to the extinction of certain species. The peppered moth case study illustrates how pollution can drive natural selection, leading to changes in species' characteristics. The video emphasizes that adaptations help organisms fit into their environments, and changes in the environment can impact entire ecosystems.

What is the primary reason pineapples cannot grow at the poles?

• Lack of sunlight

• Inadequate temperature

• Excessive rainfall

• High pollution levels

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

• Environment includes living things, ecosystem does not

• Ecosystem includes living things, environment does not

• Environment is larger than an ecosystem

• Ecosystem is a type of environment

What is an adaptation?

• A form of pollution

• A change in weather patterns

• A characteristic that helps an organism survive

• A type of ecosystem

What happened to the giant insects when the plants became extinct?

• They evolved into new species

• They adapted to the new environment

• They migrated to other regions

• They could no longer survive

What is the role of plants in the food chain?

• They are predators

• They provide shelter

• They produce chemical energy

• They decompose organic matter

Why did the giant amphibians struggle to survive after the extinction of certain plants?

• They were hunted by humans

• They lost their habitat

• They had less food available

• They couldn't adapt to the cold

How did the environment change during the Industrial Revolution that affected the peppered moths?

• Pollution darkened the trees

• Higher temperatures

• More predators appeared

• Increased rainfall

What was the result of the environmental pollution on the peppered moth population?

• Moths migrated to cleaner areas

• Both moth types were equally affected

• More dark moths survived

• More light moths survived

What happens to living things when their environment changes?

• They always become extinct

• They remain unaffected

• They adapt or change

• They migrate to new areas

What is the significance of adaptations in the survival of species?

• They prevent environmental changes

• They help species fit into their environment

• They increase the size of species

• They eliminate predators
