1. Introduction to Animals Chapter 4 7th Grade Life Science Mrs. Howard’s Class

2. Taxonomy and Classification

3. Binomial Nomenclature classification system in which each species is assigned a two-part scientific name consisting of the Genus and species Kingdom Phylum Class Order Family Genus species (King Phillip Came Over For Good Spaghetti) Taxonomy for humans would be: Animalia, Chordata, Mammalia, Primatae, Hominidae, Homo sapiens

4. Heterotrophic Eukaryotic multicellular lack cell walls >95% = invertebrates (do not have backbone) <5% = vertebrates (have a backbone) Characteristics of Animals

5. Invertebrates and Vertebrates Flatworms - Platyhelminthes Roundworms - Nematoda Segmented worms - Annelida

6. Animal Functions 1.Obtaining Food 2.Obtaining Oxygen 3.Maintaining Homeostasis 4.Movement (most animals) 5.Reproduction

7. Animal Functions Obtaining Food Carnivore (Eats animals) Herbivore (Eats plants) Omnivore (Eats both) Detritivore (Eats dead or decaying matter)

8. Animal Functions Obtaining Oxygen (Respiration) Take in O2 and give off CO2 Using lungs, gills or through skin (diffusion)

9. Animal Functions Maintaining Homeostasis Circulation/ Temperature regulation Very small animals rely on diffusion Larger animals have circulatory system

10. Animal Functions Movement: How they move can vary (swim, crawl, fly, run, slither) *Some animals don’t move at all!

11. Animal Functions Reproduction: Most reproduce sexually = genetic diversity Many invertebrates can also reproduce asexually
