ZOOLOGY 260 Final: COMPLETE FINAL NOTES-HIGHLIGHTED
Document Summary
Burying beetles: find carcass, release chemical to attract female, bury corpse and raise young, decomposition, mutualism carry around small mites that feed on fly eggs and help kill the beetles competitor. Ecology = the study of interactions among organisms and between organisms and the environment. Evolution and the diversity of life: 1) what is life, 2) darwin and evolution, 3) natural selection, 4) adaptations, 5) speciation. Bacteria- many ways to get energy: cell structure. Can be round, rod shaped, or curly cue. Lack organelles but have pilli and flagellum: chemistry. Cell wall made of meirium (penicillin stops the production of meirium) Photosynthesis (water + co2+light oxygen + carbohydrate) Anaerobic sulfate-reducing bacteria (no oxygen: hydrogen + sulfur compounds sulfide + simple compounds + energy. Purple sulfur bacteria (sulfide-oxidizing: sulfide + carbon dioxide + infrared light carbohydrates + sulfur. Cyanobacteria (blue-green algae: photosynthesis, limited by phosphorous.
