Dominance, Richness and Evenness
Dominance : form of control in a body of water to get food and proper shelter and survive long enough. Richness : The number of species per sample is a measure of richness. The more species present in a sample, the 'richer' the sample. Species richness as a measure on its own takes no account of the number of individuals of each species present. It gives as much weight to those species which have very few individuals as to those which have many individuals. Thus, one daisy has as much influence on the richness of an area as 1000 buttercups. Evenness : Evenness is a measure of the relative abundance of the different species making up the richness of an area.
