Animal Classification Quiz

Living things are organisms that possess the characteristics of life.

The main groups of living things are plants and animals.

Living things respire, feed, excrete, respond to stimuli, move, grow, and reproduce.

Classification is the process of organizing things into groups based on shared characteristics.

Features used in classifying living things include the number of legs, ways of movement, breathing methods, body covering, response to stimuli, shape, color, size, body divisions, and adaptation to the environment.

Classification helps us to easily identify and name living things.

Animals are multicellular organisms that cannot produce their own food, lacking chlorophyll.

Animals have a cell membrane, while plants have cell walls.

Vertebrates are animals with backbones.

Vertebrates have an endoskeleton, a large brain protected by the skull, and a backbone.

Warm-blooded animals maintain a constant body temperature, regardless of the surrounding environment.

Cold-blooded animals have body temperatures that fluctuate with the surrounding environment.

Mammals are vertebrates with mammary glands, which produce milk to nourish their young.

Mammals are warm-blooded, have fur, give birth to live young, and feed their offspring with milk.

Mammals give birth to live young, have fur, and have mammary glands.

Primates are mammals with well-developed brains, five fingers and toes on each hand and foot, and are omnivores.

Ruminants are ungulates that chew cud and have four-chambered stomachs.

Insectivores are mammals that feed on insects.

Chiroptera are mammals that move by flying. Their forelimbs are modified into wings, and they are nocturnal.

Marsupials are mammals with a pouch where they carry their young until they mature.

Monotremes are mammals that lay eggs.

Cetaceans are marine mammals that live in the sea and oceans.

Birds have streamlined bodies, feathers, scales on their legs, are warm-blooded, breathe through lungs, and take care of their young.

Birds of prey are carnivorous birds that hunt and kill other animals.

Perching birds have three toes forward and one toe backward, allowing them to grasp branches.

Scratching birds have strong, blunt claws for digging in the ground for food.

Swimming birds have webbed feet for swimming, flat breastbones for floating, flat beaks for scooping food, and oil glands for waterproofing their feathers.

Wading birds have long legs for wading in water, partially webbed feet for walking in mud, and long necks for spearing food.

Flightless birds are birds that cannot fly. They have weak wings and compact bones.

Climbing birds have two toes forward and two toes backward, allowing them to grip branches and climb trees.

Scavenger birds feed on carrion, or dead animals.

Reptiles are cold-blooded vertebrates with scales, lay eggs, and breathe through lungs.

Snakes are limbless reptiles with forked tongues for smelling and tasting, curved teeth for holding prey, and flexible jaws for swallowing large prey.

Amphibians are animals that live both in water and on land.

Fish are cold-blooded aquatic vertebrates with fins for swimming, gills for breathing in water, scales for protection, and streamlined bodies to reduce friction.

Invertebrates are animals without backbones.

Arthropods are invertebrates with segmented bodies and jointed legs.

Molluscs are invertebrates with soft, unsegmented bodies.

Worms are invertebrates with long, cylindrical bodies.

Echinoderms are invertebrates with radial symmetry, spiny bodies, and a water vascular system.

Sponges are simple invertebrates with porous bodies.

Sound is a form of energy produced by the vibration of objects. It travels as waves that require a medium to propagate.

Pitch is the highness or lowness of sound, determined by the frequency of vibrations.
