Kathlynn Constiner GS102 Introduction to Life Science Week 7 Assignment The Earth’s largest phylum is Arthropoda‚ including centipedes‚ millipedes‚ crustaceans‚ and insects. Insects are the largest and most successful class of animals on Earth. This success‚ zoologists believe‚ is attributed from certain biological traits such as their small size or ability to fly for some (Postlethwait & Hopson‚ 2010). The exoskeleton of most insects supports them inside but also protects them from outside. John

If not‚ which phyla have fewer than three germ layers? No‚ not all organisms on the table have three germ layers such as the sponges. The phyla’s that do have three germ layers are the: Flatworm‚ roundworm‚ mollusks‚ echinoidea‚ chordates and the arthropods. (Clc.U.C.edu. 1997) 4. One phylum on the table has more species that

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities
