Conservation and Endangered Species

The video discusses endangered species, highlighting the alarming rate of extinction due to human activities. It explains the importance of genetic variation for species survival and outlines causes of endangerment like habitat destruction and climate change. Conservation methods such as wildlife parks and seed banks are presented as solutions to protect biodiversity.

Which of the following is NOT mentioned as an endangered species in the video?

• Polar bear

• Blue whale

• Black rhino

• African elephant

What is the estimated rate of extinction due to human activities compared to natural rates?

• 10 to 100 times higher

• 1,000 to 10,000 times higher

• 10,000 to 100,000 times higher

• 100 to 1,000 times higher

What is the primary goal of conservation?

• To promote tourism

• To increase the number of zoos

• To preserve biodiversity

• To eliminate invasive species

Why is genetic variation important for a species?

• It allows adaptation to environmental changes

• It reduces the need for conservation

• It increases the risk of inbreeding

• It helps in forming emotional connections

What is a potential risk in small populations of species?

• Increased genetic variation

• Greater adaptability

• Higher chance of inbreeding

• Lower risk of extinction

Which of the following is NOT a cause of species becoming endangered?

• Climate change

• Habitat destruction

• Overfishing

• Genetic variation

What is one method mentioned for protecting endangered animals in their natural habitat?

• Introducing invasive species

• Building more zoos

• Creating protected areas

• Increasing hunting licenses

What is a disadvantage of keeping animals in captivity?

• They have more genetic variation

• There is a risk of inbreeding

• They lead a normal life

• They are less protected

What percentage of plant species are endangered according to the video?

• 80%

• 50%

• 60%

• 70%

How are endangered plant species preserved?

• By planting them in zoos

• By storing seeds in seed banks

• By increasing their genetic variation

• By introducing them to new habitats
