Students will be able to describe the diseasefight ing action of at least three pharmacologicallyactive chemicals derived from marine invertebrates Students will be able to infer why sessile marine invertebrates appear to be promising sources of new Biological elements that are used for classification of surface waters in Republic of Macedonia. 1. . In Republic of Macedonia, for classification of surface waters. , . phytobenthos. and macro invertebrates are used as biological indicators that determine the water quality. For that purpose, probes are taken 5 times during the year;. When Carl Linnaeus first created his method for organizing animals, he had just two families of invertebrates:. . Insecta. (insects) and . Vermes. (worms).. Since that time, scientists have found more invertebrates and have created more classifications. We will talk about six main categories or families of invertebrates.. Bird, frog ,sea star, shark, sponge, squid, worm, jellyfish, clam, coral and other organisms. TRY and divide them into two main categories based on classification.. List the categories and divide them organisms into two groups. Invertebrates. I can classify animals by determining if. they are vertebrates or invertebrates.. Essential Questions. • . Why do we classify animals. ?. • How do we classify animals?. Think-Pair-Share. How does invertebrate richness, diversity, and abundance change throughout an elevational gradient?. Amanda . Tynan. .
