Question 1:

Do you find that all living beings need the same kind of food?

Answer:

No. Different animals eat different kinds of food as per their body structure and internal organs. Depending on kind of food they eat, animals are divided into three basic categories:

  • Herbivores: Animals which feed on plants and plant products are called herbivores. A herbivore is an animal anatomically and physiologically adapted to eating plant material. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.

    Examples: cow, goat, elephant, dear, etc.

  • Carnivores: Animals which feed on other animals are called carnivores. At the top end of the food chain are carnivorous mammals. dogs, tigers, and lions, are all mammals that are carnivores. The prey of a carnivore varies depending on its environment, but usually a carnivore preys on a smaller carnivore, omnivore or herbivore. Domesticated carnivores like dogs and cats eat meat given to them by humans. Marine mammals such as porpoises, dolphins and whales prey on fish.

    Examples: lion, tiger, fox, etc.

  • Omnivores: Animals which feed on both plants and animals are called omnivores. An omnivore is an animal whose species gets its energy and nutrients from a diet made up foods that include plants, animals, algae, fungi and bacteria.

    Many omnivores change their eating habits during their life cycle. They are sometimes called "life-history omnivores", because they are only omnivores if their whole life is considered.

    Some species, such as grazing waterfowl like geese, are known to eat mainly animals at one stage of their lives, but plants at another. Also, many insects, such as the beetle family Meloidae, eat animal tissue when they are larvae, but eat plant matter after they mature.

    Examples: crow, cat, dog, etc.
