FAQs on Class 4 Science - Adaptation in Animals - CBSE Worksheets - 1
| 1. What are some common adaptations in animals that help them survive in their environments? |  |
Ans. Common adaptations in animals include camouflage, which helps them blend into their surroundings to avoid predators; specialized limbs, such as webbed feet in ducks for swimming; and physiological adaptations like thick fur in polar bears to withstand cold temperatures. These adaptations enable animals to thrive in their specific habitats.
| 2. How do adaptations affect the behavior of animals? | |
Ans. Adaptations can significantly influence animal behavior. For example, migratory patterns in birds are adaptations to seasonal changes, allowing them to find food and suitable breeding grounds. Additionally, nocturnal animals have adapted behaviors that allow them to hunt and navigate in low light conditions, enhancing their chances of survival.
| 3. Can you give examples of adaptations in desert animals? | |
Ans. Yes, desert animals exhibit various adaptations to survive in arid conditions. For instance, camels have developed the ability to store fat in their humps, which can be converted to water and energy. Additionally, many desert animals, like the fennec fox, have large ears that dissipate heat, while others, such as the kangaroo rat, can survive without drinking water by obtaining moisture from their food.
| 4. What is the role of natural selection in the development of adaptations in animals? | |
Ans. Natural selection plays a crucial role in the development of adaptations. It is the process by which individuals with traits better suited to their environment are more likely to survive and reproduce. Over time, these advantageous traits become more common in the population, leading to the evolution of species that are well-adapted to their environments.
| 5. How do human activities impact animal adaptations? | |
Ans. Human activities can significantly impact animal adaptations by altering habitats, introducing pollutants, and causing climate change. For example, urbanization can lead to animals adapting to new food sources, such as raccoons learning to forage in trash. However, these changes can also threaten species that cannot adapt quickly enough to survive in modified environments.
