    organisms - a living thing that can be classified as belonging to one of the five kingdoms (animal, plant, fungus, protest, moneran) 
     
    Animal Classification:
    vertebra - each bone that makes up the backbone
    vertebrates - the group of animals with a backbone
    vertebrates
       5 groups of vertebrates: 
       1. mammals (warm-blooded; have hair or fur; young are born live)
       2. birds (warm-blooded; lay eggs)
       3. reptiles (live on land; don't have gills; lizards, turtles, & snakes are reptiles)
       4. amphibians (most begin life in water, then on land; grow lungs & legs; frogs, toads, & salamanders are amphibians)
       5. fish (live in water; gills take oxygen from water)
     
    invertebrates - the group of animals without a backbone (examples include insects, centipedes, snails, & millipedes)
    invertebrates
    exoskeleton - a hard outer covering that protects an animal's body & gives it support
     
    Producers and Consumers:
    producer - a living thing, such as a plant, that can make its own food; it doesn't depend on other living thing to survive
    consumer - a living thing that can't make its own food and must eat other living things
    producer  
    Types of Consumers:
    herbivore - an animal that eats only plants, or producers (ex. rabbit, cow, giraffe)
    giraffe
    carnivore - an animal that eats only other animals (ex. jaguar, lion, hawk)
    lion
    omnivore - an animal that eats both plants and other animals (ex. turtle, bear, raccoon, monkey)
    bear
    decomposer - a living thing that feeds on the wastes of plants and animals (ex. moss, bacteria, fungi)
     
    How Living Things Get Energy:
    habitat - an environment that meets the needs of an organism
    niche - the role of an organism in its habitat
    food chain - the movement of food energy in a sequence of living things
    food chain
    prey - consumers that are eaten by producers
    predator - a consumer that eats prey
    food web - a group of food chains that overlap; shows how all the animals in a community (all the plants & animals that live in one area) get their energy
    food web
    energy pyramid - a diagram showing how much energy is passed from one organism to the next in a food chain
    energy pyramid
     
    Animal Behaviors:
    instinct - a behavior that an animal begins life with
    learned behavior - a behavior that an organism doesn't begin life with
     
    Adaptations:
    adaptation - a body part or behavior that helps an organism survive
    - Animals use adaptations to get food & water, make shelters, protect themselves, & warm up or cool down.
    camouflage - the way an animal blends in with their environment; used to hide from predators & to catch prey
    cam
    hibernation - a long sleep that some animals go through to survive the long winter; helps maintain their body temperature & reduce the amount of food needed for survival
    hibernation
