Document Summary
Biodiversity importance: water supply, prevent erosion, nutrient storage, pollution cleaning, climate stability. The higher the biodiversity, the healthier the ecosystem, and more resistance to invasive species. Threats: habitat destruction, over exploitation, competition by invasive species, and climate change. Classification: to group things in a meaningful way, for identification, for education purposes. Use of molecular evidence, anatomy and appearance, and geographical location. Carolus linnaeus: father of taxonomy, a method of grouping animals into taxons. Kingdom, phylum, class, order, family, genus, species -> kids put chocolate on father"s good shirt. Binomial nomenclature: 2 word species naming based on anatomy. Genus name: capitalized first letter, underlined or italicized on the computer. Species name: underlined or italicized if on the computer. Unicellular, asexual, nutrients through absorption, extreme conditions, anaerobes. Uses inorganic molecule and light, membrane and cells chemically unique. Fungi: multi/unicellular, no tissues, no photosynthesis, asexual, cell walls, land, absorbed nutrients. Anamalia: land/water, multicellular, no photosynthesis, ingestion, sexual but some asexual, tissues.
