Document Summary

Habitat: the place, or physical and biological setting, where an organism lives. Niche: the range of abiotic and biotic conditions an organism can tolerate. No two species have the same niche. Predation: when an organism kills and consumes an individual. Parasitism: when one organism lives in or on another organism. Competition: when two organisms that depend on the same resource have a negative effect on each other. Mutualism: when two species benefit from each other. Commensalism: when two species live in close association and one receives a benefit, and one is unaffected. System- collection of two or more interactive parts. Emergent properties- new properties emerging from the interactive combination of parts. Species- individuals that are capable of interbreeding or share genetics. Population- individuals of the same species living in a defined area. Dynamics in population size and age/sex structures. Community- interacting populations of different species in a defined area. Ecosystem- communities and their abiotic environment in a defined space.
