Alphabetical
species
[noun]
1. In biological classifications, it is the lowest and most basic unit of the Linnaean taxonomic hierarchy (although it is also divisible into subspecies), and one of the two required titles of a binomial name. In nature, a species is a group of organisms that breed only amongst themselves and produce offspring that are also capable of reproducing. 2. In chemistry, a group of constituents or molecules, that share major chemical similarities. For example, Hg0 and Hg+2, or CO and CO2.
