  1. What are living things?

  2. 5 characteristic's that living thing share • Made up of one or more cells • Respond to their environment • Use energy • Grow and mature • Living things Reproduce

  3. :Unicellular or Multicellular • Multicellular animals have more than one cell • Unicellular organisms are made up of one cell • Cells in a multicellular organisms are specialized – certain cells perform specific functions Ex. Liver cells function just for the liver • Unicellular organism – ex. An Amoeba • Multicellular organism - Lion

  4. Respond to their environment • Stimulus and Response • Stimulus – A change that affects the activity of that organism • A stimulus can be gravity, light, sound, a chemical, hunger • Response – how the organism reacts • Ex. Stimulus – your cold • Response – you get goose bumps on your arm

  5. homeostasis • The maintenance of a stable internal environment • Ex. Your body sweats when it gets too hot; sweating helps control your body temperature at a comfortable level.

  6. Living Things • Need energy to survive. • What are some ways organisms get their energy?

  7. Movement • Animals move in various ways, • Fly, swim, Run, walk • List some animals that fly, swim, walk, burrow, stationary

  8. Reproduction • animals reproduce • Sexual reproduction results in diverse offspring. Two parents • What does this mean: diverse offspring? • Asexual reproduction – single parent produces offspring whose genetic material is identical to its parent

  9. Consume Food • All animals need energy to survive. • Animals can not make their own food they must consume food – consumers. • Energy is needed to maintain body temperature. • Some animals use chemical reactions to release energy to maintain body temperature others use their environment to maintain body temp. Give an example of animal for each.

  10. Producers and Decomposers • Producers : Can make their own food • Ex. Plants through photosynthesis • They use the sun’s energy during photosynthesis • Decomposers: Break down dead organisms or waste to get their food. • Ex. Worms, bacteria, and fungi • They return nutrients to the soil

  11. What do living things need to survive? • Almost all living things need water, air, food and a place to live • Water is essential for life • Organisms often compete for food, water and a place to live

  12. Invertebrates • Animals without a backbone. • Have no bones • Exoskeleton – external covering function is to support the body • 95% of the animal population are invertebrates! • Most reproduce Asexually

  13. Invertebrates • Jellyfish • Flatworms, segmented worms • Sponges, • Others?

  14. Vertebrates • Contain a backbone • Endoskeleton – skeleton inside body • Vertebrae- protect part of the nervous system • Skull- protect brain vertebrates reproduce sexually
