What are the classifications of animals according to their feeding, displacement, and reproduction?
Classification according to feeding
Classification according to displacement
Classification according to reproduction
Animals that feed on other animals are carnivores.
Animals that feed on roots, seeds, stems, leaves, or fruits are herbivores.
Ruminants are herbivores that swallow food without chewing and later return it to the mouth to chew well.
Animals that feed on other animals, roots, seeds, stems, leaves, or fruits are omnivores.
Animals that live in the air can fly and use wings to fly.
Animals that live in the water can swim and use their fins and tail to swim.
Animals that live on land can walk, jump, or crawl, and some have legs.
Viviparous animals are born from the mother's womb and feed on their mother's milk when they suckle.
Oviparous animals are born from eggs, and oviparous animals hatch their eggs to protect and warm them.
Mammals are viviparous, have four limbs, and a body covered in hair. They can live in water or on land, breathe with their lungs, and are warm-blooded. They can be carnivores, herbivores, or omnivores.
Reptiles are oviparous, can have up to four limbs, and have a body covered in scales. They can walk, swim, or crawl, breathe with their lungs, and are cold-blooded. They can be carnivores or herbivores.
Fish are oviparous, have a body covered in scales, live in water (rivers, lakes, seas, and oceans), and can swim with their fins and tail. They can be carnivores, herbivores, or omnivores. They use scales to breathe and are cold-blooded.
Amphibians are oviparous, have a body covered in a thin layer without hair, scales, or anything to protect it. The young live in the water, and adults live on land. They breathe with lungs, gills, and even through the skin. They are cold-blooded.
Birds are oviparous, have a body covered in feathers, wings, and a beak. Almost all birds can fly, can be carnivorous, herbivorous, or omnivorous, breathe with their lungs, and are warm-blooded.
Arthropods have an articulated body that is divided into several parts. Their skin is hard and protects them. Their blood is cold. Their legs are also articulated, and many have antennae. They can be terrestrial or aquatic.
Insects have three body parts: head, thorax, and abdomen. They have six legs and two antennae. Some have wings. Flies, butterflies, and bees are insects. They are the most common animals on earth.
Arachnids have a body divided into two parts, the cephalothorax (head and thorax) and the abdomen. They have eight legs. Spiders and scorpions are arachnids.
Crustaceans have a body divided into cephalothorax and abdomen. They have two antennae, and most have ten legs, two of which are pincers. They are aquatic, like crabs.
Myriapods have a head and trunk, formed by rings. They have two antennae and more than ten legs. Centipedes and millipedes are myriapods.
