Pitch and Frequency are basically the same thing, but frequency can be quantified more easily. (Quantified is assigning a value). A piano may play a pitch of C, but the freque â¦ ncy could be 512 hertz.
Definition of speciesism. 1  1 : prejudice or discrimination based on species; especially : discrimination against animals. 2  2 : the assumption of human superiority on which speciesism is based.
Species diversity is a combination of richness and evenness; it is species richness weighted by species evenness, and there are formulae that permit the diversity of a community to be expressed in a single number.he simplest measure of a diversity is to count the number of species. This is known as species richness. Each species, however, is not likely to have the same number of individuals in that community. One species might be represented by 1000 individuals, and another by 200, and a third by a single individual.
