Document Summary
Ecology: interactions of orgs with each other and environment (biotic and abiotic) Ecological attractions (abiotic and biotic factors) affect how nature forms. Why is ecology important: determines where species are found (in part, context for evolution, management of resources: sustainability, how species we are harvesting fits into ecological context, evaluation of human impacts: we alter ecological interactions, pump. Levels of study: organismal (individual interactions with its environment), population (factors regulating population growth rates and population size), community (interactions among different species in an area), ecosystem (biotic/abiotic interactions between communities and their environments), landscape ecology, global ecology. Global processes: major processes that determine where orgs exist and how they interact, abiotic factors. Abiotic factors: some predictable attributes of communities are based on large scale abiotic factors (ie: latitudinal variation in sunlight intensity energy input and temp) Smaller range of differences in light intensity, no curvature so little or no variation in light intensity, curvature of earth determines light intensity.
