Classification Of Organisms Vocabulary Test

Welcome to the electronic frontier science classroom of the 21st century. One important branch of biology studies biodiversity, the variety of organisms considered at all levels from populations to ecosystems. This vocabulary test includes basic concepts used in many different biology textbooks. Special instructions: when a fill in type question presents itself during the course of this test. Please enter your answer(s) using all lower case letters, unless you are given specific directions to do otherwise. I wish you well in your future studies of biology and other life sciences.
