Stable environment, large body size, high parental care, mammals, humans A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. A group of populations that are separated by space but consist of the same species. These separated populations interact as individual members. High fecundity, small body size, unstable environment, dependant offspring, short life cycle, early maturity - small, reproduce fast, plants, bacteria, insects The "real" reason something occurred. Acquisition of knowledge that leads an organism to act a certain way. An instinct of an organisms to behave a certain way
