  •  Movement:  most of this is common sense. You can move around from place to place and so can most plants and animals. Animals move to:
     find shelter,
     escape from predators and other danger,
     find food,
     find a mate.
    (Plants tilt or move to face the sun.)

  • Respiration is the release of energy from glucose or another organic chemical in our cells. Respiration happens in ALL living things.

  • Sensitivity is very important. How would you know if something was fit to eat if you could not smell or taste it? How would you escape danger?

  • Growth ------ we all do it.

  • Reproduction: making more of ourselves.

  • Excretion means getting rid of the poisonous waste products produced from the chemical reactions in our bodies. We breathe out carbon dioxide and we urinate.
  • Nutrition. We have to eat to provide the materials for growth, repair and to provide us with energy.
