Shawnta used several terms in her post that I want to be sure everyone understands. Ecology is studied with a hierarchy, similar to the hierarchy of classification. The lowest level is the individual. A group of individuals of the same species that live in the same area is called a population. All of the different populations that live in the same area make up a community. So far we have only been talking about the living organisms. When you add in the non-living components of an area you have an ecosystem. The living parts of an ecosystem are called the biotic components and the non-living parts are called the abiotic components.
What are some of the abiotic components that affect what can live in an ecosystem?

Honey bees engage in entomophily, pollination through pollendistribution, as part of the process to produce honey. What isentomophily an example of?

		ecosystem
		niche
		habitat
		community

An ecosystem is composed of communities of living organisms at aparticular time. This includes plants and animals, as well asnon-living elements such as water, wind, heat, chemicalconstituents, etc. Each organism within a community has a habitatand a niche (Figure 1). An organismâs habitatisthe location in which it physically resides or is adapted toreside. An organismâs niche refers its function orâoccupationâ. Occupation defines the way in which the organismobtains and sustains all of the elements needed for survival.
