Environmental Changes and Animals

Environmental changes can significantly impact animal survival, requiring them to adapt or relocate. Historical events like the extinction of dinosaurs highlight the consequences of failing to adapt. Modern examples include the decline of golden toads due to El Nino and the adaptation of German Blackcap birds and Gentoo penguins to climate changes. Some species, like Edith's checkerspot butterflies and certain corals, relocate to survive. Overall, animals must adapt or move to meet their needs in changing environments.

What is a major consequence for animals that fail to adapt to environmental changes?

• They become more diverse.

• They become predators.

• They thrive in their current habitat.

• They face extinction.

Which event is believed to have contributed to the extinction of dinosaurs?

• A severe drought

• An asteroid impact or climate change

• A massive volcanic eruption

• A global flood

How have German Blackcap birds adapted to rising temperatures in Central Europe?

• By migrating earlier to start nesting sooner

• By moving to higher altitudes

• By changing their diet

• By migrating later in the year

Which penguin species has successfully adapted to warmer temperatures in the Antarctic region?

• Chinstrap penguin

• Gentoo penguin

• Adelie penguin

• Emperor penguin

Why are Edith's checkerspot butterflies moving further north into Canada?

• To find more food

• To find new mates

• To avoid warmer temperatures in the south

• To escape predators
