Used for non-mobile animal species or plant species Pooter Allows small animals to be sucked into an observation chamber so they can be more easily identified Net Used in long vegetation or in streams and rives to catch small organisms for the purpose of identification Abiotic non-living Biotic living Classification allows a better understanding of evolution, biodiversity and how best to conserve species for future generations. Chordates Animals with backbones: (MR FAB) mammals, reptiles, fish, amphibians, birds Insects Animals with an exoskeleton and a body divided into three sections (head, thorax and abdomen), two pairs of wings, three pairs of jointed legs, body temperature not constant Annelids Animals with a segmented body and hairlike structured called chaetae for grip, body temperature not constant Flowering Plants Plants with true roots, stems and a highly developed vascular system. Rely on flower, seed and fruit production to facilitate reproduction. Protoctista - saprophytic or photosynthetic nutrition - cellulose or no cell wall - single-celled with nucleus - hard to classify because some organisms have both animal and plant characteristics Bacteria -saprophytic nutrition
