APES Unit 2 reviewKeystone species - correct answer Species that plays large role in affecting many other species in an ecosystem Invasive species - correct answer Species that migrate or are introduced into an area Extinction - correct answer Complete disappearance of a species from Earth. Species are unable to reproduce or a species evolves into one or more new species Carrying capacity - correct answer Maximum population of a particular species that a given habitat can support over a given period Island biodiveristy - correct answer The number of different species on an island is determined by the rate of migration to the island and how close it is to the mainland Adaptation - correct answer A genetically controlled characteristic that helps an organism survive and reproduce under a set of environmental conditions 4 parts of biodiiveristy - correct answer genetic diversity, species diversity, functional diversity, and ecological diversity Hot spots - correct answer Areas especially rich in plant species that are found nowhere else and are in greater danger of extinction Biotic - correct answer Living organism Commensalism - correct answer Interact between species in which one organism benefits and the other is neither helped or harmed Ecological succession - correct answer Process in which communities of species in a particular area are replaced over time by a series of different and more complex communities Endemic Species - correct answer Species only found in one area. Vulnerable to extinction Generalist species - correct answer Species with a broad ecological niche habitat fragmentation - correct answer Breakup of a habitat into smaller pieces, usually as a result of human activities. HIPPCO - correct answer Habbitat destruction, degradation, and fragmentation; Invasive (nonnative) species; Population growth (too many people consuming too many resources); Pollution; Climate change; and Overexploitation Indicator species - correct answer species that serve as early warnings that an ecosystem is being damaged Intrinsic rate of increase - correct answer rate at which the population of a species would grow if it had unlimited resources K-selected species - correct answer Species that produce a few, often fairly large offspring but invest a great deal of time and energy to ensure that most of those offspring reach reproductive age. mutualism - correct answer A relationship between two species in which both species benefit Parasitism - correct answer A relationship between two organisms of different species where one benefits and the other is harmed Pioneer species - correct answer First species to begin colonizing a site Reproductive isolation - correct answer Long-term geographic separation of members of a particular sexually reproducing species.
