1 Flyswatter Review Community all the populations of organisms inhabiting a common environment and interacting with one another Interspecific interactions occur between populations of different species Coevolution a change in one species acts as a selective force on another species Symbiosis For at least part of the life cycle, individuals of two or more species interact with neutral, positive. Or negative effects on each other Niche a way of life, or a role in an ecosystem. an organism s role in the environment (its profession, not its address) Fundamental niche determined by the physiological limits of the organism Realized niche the portion of the fundamental niche actually utilized due to interactions with other species Interspecific Competition ( / ) Competition occurs when 2 or more populations overlap in their niches Resource partitioning The subdividing of some category of similar resources that lets competing species coexist. Predation (+/ ) consumption of one organism by another Parasitism (+/ ) specialized predator (parasite) lives on/in its host, not killed immediately Endoparasitism live inside host (tapeworms/viruses) Ectoparasitism live on surface of host (mosquitoes/aphids) Commensalism (+/0) one partner benefits while not harming the other Mutualism (+/+) both partners benefit. Camouflage A coloration that helps organisms blend it with their surrounding environment. Warning Coloration A coloration characterized by conspicuous patterns and colors that predators learn to recognize and avoid.

2 Batesian mimicry Imitate color patterns or appearance of more dangerous organisms Müllerian mimicry describes a situation where two or more species have very similar warning or aposematic signals and both share genuine anti predation attributes. Producers Organisms capable of making their own food. Primary consumers Eat plants and capture their energy Secondary consumers Eat primary consumers Herbivores organisms that eat only plants Carnivores organisms that eat only meat Omnivores organisms that eat both plants and meat. Decomposers break down waste and dead organisms Trophic Level The different levels of organisms on a food chain, based on what they consume. Rule of 10 Each time an eating event occurs, only 10% of that energy is available for use by the consuming organism. Bioaccumulation The increase of a toxin in an organism over time Biomagnification The increase of a toxin in an organism as you go up the food chain. Invasive Species: a species that is non native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm, or harm to human health. Cilia Hair like projections used for movement and feeding Flagella Whip like structure used for movement Pseudopod A false foot extended by cytoplasm Algae A small plant like protist that can make it s own food
