Levels of Organizations in Ecosystems

Species/ individual/ organism �The individual living organism �Organisms of the same species can reproduce to make more of that species � Example– one white tail deer

Populations �All of the individuals of a given species in a specific area or region at a certain time. �Members of a population compete for food, water, space, and mates �Example – all of the white tail deer in South Carolina

Communities different populations in a �All the specific area or region at a certain time. �Communities involve many interactions among the populations. types of �Some of these interactions involve the obtaining and use of food, space, or other environmental resources. Example – all of the living organisms (biotic factors) in the environment with the white tail deer, including pine trees, grass, squirrels, moss, mushrooms, and Carolina wrens.

Ecosystem �One or more community in an area and the abiotic factors, including water, sunlight, oxygen, temperature, and soil. Example – all of the living organisms (biotic factors) in the environment with the white tail deer, including pine trees, grass, squirrels, moss, mushrooms, and Carolina wrens as well as all of the abiotic (non-living) factors such as rivers, soil, air, and rocks

Biome �Individual ecosystems grouped together according to the climate and the predominant vegetation and characterized by adaptations of organisms to that particular environment. Example – the temperate deciduous forest that the white tail deer lives in.

Within an Ecosystem �Habitat: where an organism lives the place in order to obtain its food, water, shelter and other things needed for survival. �Niche: role of an organism The particular in its environment including type of food it eats, how it obtains its food and how it interacts with other organisms. For example, the niche of a bee is to pollinate flowers as it gathers nectar for its food.
