Science 7-1 Mrs. Archer Name_______KEY________________ Taxonomy - the science of classifying and naming living things (organisms) A. When deciding which group a living thing belongs in, taxonomists look at four traits or factors: Body structure and fossil evidence ex: Does it have bones? Body chemicals ex: Does it have chlorophyll? Behavior ex: How does it respond? Food needs ex: How does it get food? B. Every organism is assigned to a “kingdom ” group: Draw 2 examples here: 1. Plants - producers, make own food, multicellular, no locomotion 2. Animals – consumers, Two Examples: cannot make own food, multicellular, has locomotion Draw 2 examples: 3. Moneran (Bacteria) - one simple cell (unicellular), no nucleus 4. Protists - one complex cell (unicellular) with a nucleus 2 Examples: 2 Examples: 5. Fungi – decomposers and recyclers, absorb food from other organisms What is Biodiversity? – the rich variety of life in every ecosystem on earth 3 Kinds of Biodiversity 1. Variety of genes – compare a poodle with a golden retriever 2. Variety in speciesCompare pansies with pillbugs! 3. Variety of ecosystems- desert, prairie, ocean, forest, swamp…. Is Biodiversity good for kids? YES! It gives you: • air to breathe • food to eat •clean water •M_________ •Clothes, shoes, paper, etc •Earth’s ________________ What is happening to biodiversity? It is being damaged, due to: The HIPPO dilemma: •Habitat loss •Invader species •Pollution •Population growth •Over -consumption Think: How can YOU help maintain biodiversity? D. Every living thing that has been discovered has been classified and given an international name. This is a scientific name, made of two parts, genus and species. Sometimes there is a third name, a subspecies. Using the Zoobooks provided in class, locate 4 scientific names of animals and write them below. Scientific Name Common name 1. Genus species subspecies 2. 3. 4. E. Taxonomic key- a series of paired statements that describe the characteristics of different organisms. See p. 188 in textbook Can you list the five kingdoms of living things? F. Kingdoms are broken down into smaller groups: Memory trick: King Example: human Kingdom Animal Phillip Phylum Chordate Came Class Mammal Over Order Primate For Family Hominidae Grape Genus Homo Scientific name Soda species sapiens G. Historical person to know: Carolus Linnaeus (1700’s) – used Latin to create a scientific naming system - now used internationally
