SOLVED - Elaborated AP Environmental Science-Unit 2 V1-2023Biodiversity - Ans | > the number, variety, and variability of Earth's organisms that consists of three level of diversity Species Diversity... - Ans | > number of different species (species richness) combined with the relative abundance of individuals within each of those species (species evenness) Genetic Diversity - Ans | > variability in the genetic makeup among individuals within a single species and is vital to the sustainability of life on Earth Ecosystem Diversity - Ans | > Earth's variety of deserts, lakes, oceans, forests, wetlands, coral reefs, etc. Ecosystem Services - Ans | > important environmental benefits provided to people such as clean air and water and fertile soil Extinction - Ans | > the elimination of a species from Earth Endangered Species - Ans | > a species that faces threats that may cause it to become extinct within a short period of time Threatened Species - Ans | > a species whose population has declined to the point that it may be at risk of extinction Endemic - Ans | > species not found anywhere else Genetic Resistance - Ans | > the ability of one or more organisms in a population to tolerate a chemical designed to kill it (Ex: antibiotics and bacteria) Habitat Fragmentation - Ans | > the breakup of large areas of habitat into small isolated patches and is a major threat to long-term survival of many species Biodiversity Hotspot - Ans | > relatively small areas of land that contain an exceptional number of endemic species that are at high risk from human activities Invasive Species - Ans | > foreign species that spread rapidly in a new area where they are free of predators, parasites, or resource limitation that may have controlled their populations in their native habitat Biotic Pollution - Ans | > the introduction of a foreign species into an ecosystem in which it did not evolve; often upsets the balance and interferes with functioning in the ecosystem.
