Document Summary
Birth rate live children born in one year/ midyear populaiton in same year. Death rate deaths in one year/midyear populaiton in same year. Average number of kids each women has over her lifetime. Carrying capacity maximum population of a species that a given habitat can support without being degraded. Biotic and abiotic factors that may limit a populations increase. Recruitment survival through early growth stages to become part of the breeding population. K strategist few offspring, long life span, typically larger organisms. R strategist many offspring, short life span, smaller organisms. Mutualism arrangement between two species where both benefit. This species plaays a crucial role in maintaining ecosystem biotic structure. Primary succession process of initial invasion and progression from one biotic community to another. Secondary succession an area cleared by some disturbance is reinvaded by plants and animals from surrounding areas. Disturbance a significant change that kills or displaces many community members.
