Document Summary

Species classifying, distribution, issues with defining what a species is. Explain, in general terms, how the earth"s shape affects the intensity of solar radiation across latitudes. Define the three different types of biodiversity (species, community/ecological, genetic). Species: the number of species in an ecosystem. Community/ecological: the number of communities in an ecological system. Genetic: the number of alleles in a species. Define (terms describing the hierarchy of life): biosphere, ecosystem, community, population, multicellular organism, and cell. Ecosystem: group of communities interacting in their shared environment. Biosphere: all regions of earth that sustain life (includes all things biotic and abiotic). Community: populations of species that occupy the same area. Multicellular organism: organism consisting of multiple cells. Population: group of organisms that belong to the same species. Use the terms species, individual and organism appropriately. Species: lowest in hierarchy of the eight taxonomic ranks. Often defined as a group of organisms capable of interbreeding and producing fertile offspring.
