Classification Carolus Linnaeus The process of organizing living things into groups so that they can be studied more easily. 18th Century Swedish botanist who devised a system of classifying and naming organisms Binomial Nomenclature The practice of giving every living thing a two word name based on its genus and species The 7 divisions of the Lennaean Classification System 1. 2. 3. 4. 5. 6. Scientific Name Kingdom Plylum Class Order Family Genus 7. Species A two-word name of an organism derived from its genus and species (The first letter of the genus name is capitalized. The first letter of the species name is lower case.) Branching Tree 6 Kingdoms of Living Things Characteristics used to classify organisms into kingdoms A diagram that shows the evolutionary pathways and relationships among organisms 1. 2. 3. 4. 5. Eubacteria Archaebacteria Protist Plants Fungi 6. Animals Cell structure Number of cells How they obtain food Autotrophs Organisms that can make their own food using carbon dioxide and water. (Photosynthesis and chemosynthesis are two food-make processes of autotrophs.) Plants are autotrophs. Heterotrophs Organisms that cannot make their own food. They have to get their food. Animals and fungi are heterotrophs. Organisms that have their genetic material enclosed in in a nucleus Eukaryotes Prokaryotes Organisms that do not have their genetic material enclosed in a nucleus Unicellular Multicellular Biodiversity Niche Community Ecosystem Organisms that consist of one independent cell. The single cell carries on all life activities. Organisms that are made up of more than one cell The amazing variety of living things on Earth An organism’s role in its environment An integrated group of species that live in a specific area. They influence each other is several ways. The living members of a habitat interacting with their non-living environment, such as rocks, water, etc. Main reasons why organisms Habitat destruction Invasive species become extinct Pollution (HIPPO) Poaching Overharvesting/overpopulation Characteristics of Living Things Needs of Living Things Captive Breeding Living things are made of cells, are composed of specific chemicals, use energy, grow and develop, respond to their environment, and reproduce. Living things need a source of energy, water, living space, and a stable internal environment (homeostasis). Conservation program that involves breeding endangered animals for the purpose of releasing the offspring into the wild
