Animals are many-celled organisms that are made up of different kinds of cells.
Three Different Traits of Animals • Shape • Size • Color
Four Basic Needs of Animals • Food • Water • Shelter • Space
Animal Cells • Nucleus and specialized structures • Organized to form systems • Enable animals to perform different functions: • Sensing the environment • Getting rid of wastes • reproducing
Animals CAN’T make their own food. • Eat plants • Eat animals • Eat both plants and animals
Most animals can move from place to place to find food/water, shelter, mates, and to protect themselves from predators.
Animals eat different food. • Octopuses: Tentacles • Frogs: Long and sticky tongue
Animals are divided into two groups. • Vertebrates: Group of animals that have backbones. • Invertebrates: Group of animals with no backbone.
Fish • Vertebrate that lives its whole life in water • Most diverse vertebrate group • Gills to breathe • Covered by scales
Amphibian • Vertebrate that lives part of its life in water and part of its life on land • Thin, moist skin • Most have four legs
Reptile • Egg-laying vertebrate with thick, dry skin • Snakes, turtles, alligators, and lizards • Covered with scales • Breathe with lungs
Bird • Vertebrate that has both feathers and wings • Hollow bones • Air sacs to help them fly
Mammals • Vertebrate that feeds its young milk • Humans
Invertebrates • A. Sponge: simplest kind of animal • G. Arthropods: Biggest group of animals
Mimicry • Protected against predators by its resemblance to another, unpleasant animal
Camouflage • blending in with the environment • Shape • Color • Protective Coloration: A type of camouflage
What is inherited? • Inherited: Passed down from one generation to the next • Instinct: Inherited behavior • Heredity: Passing down of inherited traits from parents to offspring
D. Inherited Behavior: Young birds building nests like their parents E. Inherited Physical Trait: • Color of a bird’s feathers • Shape of a bird’s feet F. Trait Not Inherited • Animal’s weight • Animal’s size
Learned Behavior • Dog that goes to the door when owner picks up its leash
Hybrids • Crossing of parents that have different forms of the same trait
Crossbreeding • mating two distinct breeds or varieties of the same species • Healthier and live longer
Diversity • Wide variety of traits in dividuals from the same population
