FAQs on Adaptation In Polar Regions Video Lecture - Class 7 Oxford Science: Chapter Notes, Worksheets & Tests

1. What are some examples of adaptations in polar regions?
Ans. Some examples of adaptations in polar regions include thick fur or blubber to provide insulation, white fur or feathers for camouflage, compact body shape to minimize heat loss, and specialized blood circulation to keep extremities warm.
2. How do animals in polar regions find food in such extreme conditions?
Ans. Animals in polar regions find food by various means. Some animals, like polar bears, rely on hunting seals by waiting near breathing holes in the ice. Others, like penguins, feed on fish and krill that live in the surrounding ocean. Some animals, like Arctic foxes, scavenge on the remains of other animals.
3. How do plants adapt to survive in polar regions?
Ans. Plants in polar regions have adapted to survive in extreme cold and limited sunlight. They often have small, low-growing structures to conserve heat and reduce wind damage. Some plants have also developed the ability to photosynthesize through their stems or leaves to maximize their exposure to sunlight.
4. How do animals in polar regions protect themselves from predators?
Ans. Animals in polar regions protect themselves from predators through various adaptations. Some animals, like Arctic foxes, change their fur color with the seasons to blend in with their surroundings. Others, like seals, use their agility and speed to escape from predators in the water.
5. What challenges do human beings face in the polar regions?
Ans. Human beings face numerous challenges in polar regions, including extreme cold, limited resources, and isolation. They need to have proper clothing and equipment to protect themselves from the harsh environment. Travel and transportation can also be difficult due to the icy conditions. Additionally, the polar regions are vulnerable to climate change, which can further impact human activities and settlements.
