Short Answer Questions
Q1: What are terrestrial animals?
Ans: Terrestrial animals are animals that live on land. They can be found in many places like forests, deserts, and mountains. Some examples are dogs, tigers, and goats.
Q2: What are aquatic animals?
Ans: Aquatic animals are animals that live in water. They can be found in oceans, rivers, and lakes. Examples include fish, dolphins, and turtles.
Q3: What do herbivores eat?
Ans: Herbivores only eat plants. They enjoy eating leaves, fruits, and vegetables. Some examples of herbivores are cows, rabbits, and elephants.
Q4: What do carnivores eat?
Ans: Carnivores eat the flesh of other animals. They hunt and catch animals for food. Tigers and lions are examples of carnivores.
Q5: What is an omnivore?
Ans: An omnivore is an animal that eats both plants and meat. Bears and foxes are examples of omnivores because they eat fruits and also hunt for animals.
Q6: How do birds fly?
Ans: Birds fly using their wings. They have light bones and feathers that help them take off and stay in the air. Some birds, like ostriches, cannot fly because their wings are small.
Q7: What is animal migration?
Ans: Animal migration is when animals move to different places at certain times of the year. They do this to find food, water, or a safe place to have their babies.
Q8: How do fish breathe underwater?
Ans: Fish breathe underwater using their gills. Gills take in oxygen from the water. As water flows over them, the fish can absorb the oxygen they need to live.
Q9: What helps insects breathe?
Ans: Insects breathe through tiny holes called spiracles. These holes lead to tubes that carry air to their bodies so they can breathe.
Q10: What are some ways animals move?
Ans: Animals can move in different ways. Some animals fly, like birds. Others swim, like fish. Some walk or run, like dogs. Some hop, like frogs and kangaroos.
Q1: Explain the process of breathing in fish.
Ans: Fish breathe using gills. They take in water through their mouths, and as water passes over the gills, oxygen dissolved in the water is absorbed into the blood. The oxygen is then transported throughout the fish’s body. The water, after releasing oxygen, flows out through a flap, completing the process.
Q2: What is migration, and why do animals migrate? Provide examples.
Ans: Migration is the regular, long-distance movement of animals to find food, water, escape harsh weather, or find suitable places for reproduction. For example, bar-headed geese migrate to India during winter and return to the Himalayan mountains in summer. Whales migrate to colder parts of the ocean for feeding and to warmer waters for giving birth.
Q3: How do insects breathe? Explain the role of spiracles.
Ans: Insects breathe through small openings on their bodies called spiracles. Spiracles lead to a network of tiny tubes called tracheae, which deliver oxygen directly to the insect’s cells. This system allows efficient oxygen exchange without the need for lungs. Examples of insects that use spiracles include bees, grasshoppers, and butterflies.
Q4: Describe the feeding habits of herbivores with examples.
Ans: Herbivores are animals that eat only plants. They have broad, flat teeth designed for chewing plant material. Examples include rabbits, cows, goats, elephants, and tortoises. These adaptations help herbivores efficiently consume leaves, grass, fruits, and other plant parts.
