Animal Survival Strategies: Hibernation, Dormancy, and Brumation Explained

The video explains how animals adapt to winter through hibernation, dormancy, and brumation. Hibernation involves deep sleep and reliance on fat reserves, seen in hedgehogs and bats. Dormancy, observed in bears and squirrels, allows periodic waking to eat. Brumation, a state of torpor, occurs in reptiles and amphibians. Each adaptation helps animals survive food scarcity and cold temperatures.

Why do some animals enter a state of hibernation during winter?

• To escape predators

• To conserve energy due to food scarcity

• To migrate to warmer regions

• To reproduce

What is the primary difference between hibernation and dormancy?

• Dormancy involves migration

• Hibernation involves constant sleep

• Dormancy involves constant sleep

• Hibernation involves regular waking

Which of the following animals is known to hibernate?

• Hedgehog

• Raccoon

• Squirrel

• Frog

How do hedgehogs prepare for hibernation?

• By increasing their body temperature

• By finding a cozy shelter

• By storing food in their dens

• By migrating south

What is a unique behavior of the edible dormouse before hibernation?

• It migrates to a warmer climate

• It stores food in tree crevices

• It digs into the ground and rolls up like a ball

• It triples its weight

Which animal is known to enter a state of dormancy?

• Hedgehog

• Brown bear

• Bat

• Tortoise

How do squirrels ensure they have enough food during dormancy?

• By storing nuts in the ground or tree crevices

• By eating continuously

• By hibernating

• By migrating to warmer areas

What is brumation?

• A type of hibernation for mammals

• A state of torpor for reptiles and amphibians

• A migration pattern for birds

• A feeding behavior in winter

Which of the following animals undergoes brumation?

• Hedgehog

• Bat

• Raccoon

• Frog

What is a key characteristic of brumating animals?

• They have a high metabolism

• They remain active throughout winter

• They migrate to warmer regions

• They have a very slow metabolism and low body temperature
