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?

Which of the following scenarios would most liekly lead to resource partioning and consequently contribute to ecosystem stability?
