Understanding Extinction and Its Prevention

What is the primary definition of a species being extinct?

• When a species is endangered

• When a species has no living individuals left anywhere

• When a species is no longer found in a specific region

• When a species is only found in captivity

Which of the following is a natural cause of extinction?

• Pollution

• A species' inability to adapt to environmental changes

• Introduction of new predators

• Deforestation

How can the introduction of a new predator lead to extinction?

• By changing the climate

• By hunting or out-competing native species

• By causing diseases

• By increasing the prey population

What human activity is a major contributor to climate change?

• Using renewable energy

• Recycling

• Burning fossil fuels

• Planting trees

Which of the following is a direct result of habitat loss?

• Improved air quality

• Extinction

• Species adaptation

• Increased biodiversity

Which species was primarily driven to extinction by hunting?

• Blue whale

• Passenger pigeon

• Dodo

• Bengal tiger

What is one method to prevent extinction through breeding?

• Introducing new predators

• Creating seed banks

• Developing breeding programs in zoos

• Increasing deforestation

How do seed banks help in preventing plant extinction?

• By introducing new plant diseases

• By cutting down trees

• By increasing greenhouse gas emissions

• By storing seeds for future planting

What is a benefit of reducing greenhouse gas emissions?

• Prevention of some species from going extinct

• Higher global temperatures

• More deforestation

• Increased habitat loss

Why is recycling important in preventing extinction?

• It causes more pollution

• It reduces habitat loss by minimizing resource extraction

• It increases the need for natural resources

• It leads to more deforestation
