Species - A group of living organisms consisting of similar individyals capable of exchanging genes or interbreeding.
Species compete with each other for food, water, living space and other resources. Each organism plays one of three roles: producer, consumer, or decomposer. Communities vary in size, do not have precise boundaries, and are hardly isolted. Communities exist within communities. There are two types of ecosystems: natural in which are operated under natural conditions and artificial ecosystems in which are controlled by humans. Ecosystems consist of biotic (living) components and abiotic (nonliving) components. Functions of ecosystems include: trophic level interaction, ecological succession, and bio geochemistry.
