Animal Adaptations and Survival Strategies

The video explains the concept of adaptation in living beings, highlighting how species develop the ability to survive in different environments through morphological, physiological, and ecological changes. Morphological adaptations involve physical changes like the elongated neck of giraffes or the spines of cacti. Physiological adaptations include metabolic changes, such as hibernation in bears. Ecological adaptations focus on behavioral changes, like the migration of monarch butterflies. These adaptations are crucial for survival and reproduction, often taking numerous generations to develop and are irreversible.

What is the primary purpose of adaptation in living beings?

• To become extinct

• To increase their size

• To survive in different environments

• To change their color

Which of the following is an example of morphological adaptation?

• Accumulation of fat in polar bears

• Hibernation in mammals

• Sharp claws and teeth in lions

How do cacti adapt to extreme environments?

• By growing taller

• By developing thick leaves

• By producing more flowers

• By having spines instead of leaves

What is the function of the camel's thick fur?

• To attract mates

• To store water

• To protect from the sun

• To help in swimming

Which adaptation helps giraffes to feed on high tree leaves?

How do polar bears conserve heat?

• By growing longer fur

• By accumulating fat under their skin

• By changing their color

• By migrating to warmer areas

What is estivation?

• A method of hunting

• A form of hibernation during summer
