The video explores the importance of freshwater and how living organisms adapt to varying water availability. It highlights the scarcity of freshwater on Earth, using Lake Baikal and the Sahara Desert as examples. In Lake Baikal, the nerpa seal has adapted to its freshwater environment, while in the Sahara, the addax antelope has adapted to survive with minimal water. The video concludes that organisms can thrive in different environments through specific adaptations.

What analogy is used to describe the amount of freshwater available on Earth?

• A teaspoon in a gallon jug

• A drop in the ocean

• A cup in a swimming pool

• A spoonful in a lake

Which animal is highlighted as an example of adaptation in Lake Baikal?

• Walrus

• Penguin

• Nerpa seal

• Polar bear

How do nerpa seals adapt to the icy conditions of Lake Baikal?

• By migrating to warmer areas

• By using their strong flippers to create breathing holes

• By hibernating during winter

• By growing thicker fur

What is a unique adaptation of the addax antelope in the Sahara Desert?

• Storing water in its hump

• Changing the color of its coat

• Growing longer legs

• Developing webbed feet

Why do many animals in the Sahara rarely need to drink water?

• They have a diet rich in water

• They migrate to water-rich areas

• They are nocturnal

• They have adapted to conserve water
