Document Summary
Population is individual who combine of the same species. Community is population of different species interaction (ex: pond includes plants, frogs, insects, fish etc) Communities interact with each other, with other biotic/abiotic process to form ecosystem. Habitat is a space in which individuals to species carry out their everyday lives. How an organism uses it habitat & way it utilizes the resources within is called its ecological (cid:862)niche(cid:863) Between members of different species=interspecific; members of same species=intraspecific interference competition: individuals interacting with each other over access to the resource. Exploitative competition: direct competition (when 1 organism comes and feeds on all the fruit b4 another one can) each organism is exploiting the resource than can be uses by another. How species share resources: similar species share the same area usually divide up resources using a method called partitioning. Each species specialize in harvesting one particular subset of the resource. Occurs when a predator feeds on its prey.
