Document Summary

Interaction between organisms and their non living environments abiotic interactions. Allow biologists to derive hypothesis about how systems function. Ecological phenomena occur over long time spans and huge areas (ex: global warming/ climate change) Ecology divided into 4 levels of organization: Organismal ecology individual levels, natural selection acts upon the organism study this to determine genetic, biochemical, physiological, morphological, and behaviour adaptations to abiotic environment. Focus on groups of individuals of the same species that live together. Study how size and other characteristics of population change in space and time. Examine populations of different species in one area. Study interactions between species how predation, competition & environmental disturbances influence a community"s development/ organization/ structure. Ecosystem ecology including abiotic resources, climate, nutrients etc. abiotic and biotic factors interacting together. How nutrients cycle and energy flows between biotic components of an ecological community and the abiotic factors. Ex: global warming is a biotical caused problem.
