Document Summary
What is ecology: divided into sub-disciplines, hierarchy, other categories. Community ecology: a community is a group of interacting populations of different species in an area, community ecology deals with the whole array of interacting species in a community. Ecological interactions: organisms and environment, species distribution, range limitations, environment is composed of, biotic factors, abiotic factors. Biotic factors: organisms interacting with other species. Interactions can be positive, negative, or neutral: plant/ pollinator, predator/ prey, herbivore/ plant. Ecosystem ecology: a community of organisms with the biotic and abiotic interactions, ecosystem ecology emphasizes energy flow and chemical cycling among the various biotic and abiotic components, movements of carbon, nitrogen, and other elements, climate change. Temperate deciduous forests have abundant life: temperate deciduous forests, found south of the taiga in eastern north america, eastern asia, and much of. Autumn fruits, nuts, and berries provide food for the winter. Leaves, falling to the ground, contribute to a rich layer of humus.
