  1. Five Characteristics animals have in common
    1. They are made of many cells. 2. They reproduce 3. They move in some way. 4. They grow and change. 5. They eat food.
  2. Know these steps of the food chain in the correct order:
    • 1. Energy comes form the sun.
    • 2. Producers use sunlight to make food.
    • 3. Consumers that eat plants are primary consumers. They use some of the energy to stay alive. The rest is lost as heat.
    • 4. Secondary consumers get energy by eating other consumers.
    • 5. After organisms die, decomposers like fungi and bacteria break down their remains into chemicals.
  3. Two sides that are mirror images. Hint: A person has this.
    bilateral symmetry
  4. Body parts extend outward from a central point and match up. Hint: like a star fish.
    radial symmetry
  5. There is no dividing line or line of symmetry
  6. An animal whose body temperature changes according to its environment
    cold-blooded animal
  7. An animal WITH a backbone
  8. An animal with this has bones inside its body that support it
    endoskeleton (endo or inner skeleton)
  9. an animal WITHOUT a backbone
  10. An animal WITH a constant body temperature that DOES NOT change
    warm-blooded animal
  11. An animal with this has a hard covering to protect its body
    exoskeleton (exo or exterior skeleton)
  12. Name 5 invertebrates.
    sponge, sea star, butterfly, earthworm, jellyfish, insect, crab
  13. Name 5 vertebrates bird, cheetah,
    human, snake, elephant...
  14. The simplest invertebrate: It's body has no symmetry, only 2 cell layers and filters the water trapping tiny food particles
  15. An animal that shoots poison darts, has poison stingers, and uses tentacles to catch prey or protect itselves. They have radial symmetry, a mouth and simple tissues.
  16. More complex than the sponge and cnidarians, they have flat, ribbonlike bodies with a head and tail, and have bilateral symmetry and 3-cell layers.
  17. They have a slender, rounded body with pointed ends. Many of these attach themselves to a plant or animal for food. This food goes in throught one hole in the body and the waste comes out a hole in the opposite end.
  18. Their bodies are divided into sections (called segments) and have a 3-layer body with bilateral symmetry. These also have a digestive system with two openings.
    segamented worms
  19. These are soft-bodied invertebrates with a seashell. Some of them have internal shell-line structures.
  20. A spiny-skinned animal (usually with a star design)
  21. They have an endoskeleton usually with protective spines and tiny tube feet like suction cups.
  22. The largest of all animal phyla or grouping of organisms that have the same body plan: They have jointed legs and the body is divided into sections. They have a hard skeleton on the outside of the body called an exoskeleton.
  23. _________ spends part of its life in water and part on land. They are cold-blooded. Their skin is usually damp and will dry out without water. They are found in wet or damp places... Frogs, toads, salamanders...
  24. These have dry scales on their skin or large plates, strong waterproof skin to help them live on land. They are cold-blooded. Their skin keeps water from escaping out of their body. They lay eggs with a rougher shell than an amphibian. Turtles, lizards, snakes, alligators, and crocodiles
  25. _____ are covered with feathers, have beaks, no teeth, two legs with clawed feet and wings. They are also warm-blooded, lay eggs with hard shells and keep their eggs warm until they hatch.
  26. These are warm-blooded, have hair and can learn. In these, the females can produce milk to feed their young.
