التنوع والتكيف فى الكائنات الحية: التكيف مع ظروف الطقس

The video discusses how animals adapt to cold climates through hibernation, migration, and physical changes. Hibernation involves storing fat for energy during long winter sleeps. Migration is another strategy, with many birds and mammals traveling long distances to find food and warmth. Some animals, like gazelles, grow thicker fur for insulation, while others, like weasels, change fur color to blend with snowy environments. These adaptations help animals survive harsh winter conditions.

What is the primary purpose of animals storing fat before hibernation?

• To attract mates

• To have energy reserves for the winter sleep

• To stay warm during the winter

• To build muscle mass

Which of the following is a reason why animals migrate during winter?

• To find new territories

• To enjoy warmer weather

• To escape predators

• To search for food and shelter

How do deer adapt to cold weather in winter?

• By changing their diet

• By growing thicker fur

• By migrating to warmer areas

• By hibernating

What change occurs in some weasels during winter?

• They start hibernating

• They change their fur color to white

• They grow longer tails

• They develop larger ears

Why do some weasels in southern regions not change their fur color in winter?

• They do not need to blend in with snow

• They prefer to stay warm

• They migrate instead

• They are a different species
