Reading Two 1. Glycogen is a storage molecule for simple sugars characteristically found in animals . 2. The movement of water through plants is called transpiration . 3. Sulfur dioxide is released when coal is burned. 4. The main molecule in forming acid rain is sulfuric acid. 5. Some authors claim that ecological efficiencies between trophic levels are roughly 10% . 6. The Lithosphere refers to the earth’s crust. 7. In Elton’s pyramid scheme for representing trophic levels in a community, the size of each box represented the amount of biomass at a trophic level. 8. Sulfur dioxide is found in the atmosphere . 9. Phosphorus is the element not found in amino acids or proteins. 10. Some species of bacteria convert ammonia to nitrites and others convert it to nitrates in the process called Nitrification . 11. Photosynthesis is the process in which carbon fixation occurs. 12. The main difference between the sulfur and phosphorus cycles is that the sulfur cycle has an atmospheric component . 13. The phosphorus cycle is an example of a sedimentary cycle. 14. Sulfur is the sixth important element in forming the molecules of life in addition to the elements of Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus. 15. Carbon fixation occurs typically in plants . 16. Denitrification occurs in the absence of oxygen . 17. The breakdown of animal and plant amino acids by bacteria is called ammonification . 18. In the process of aerobic respiration simple sugars are broken down to form carbon dioxide and water. 19. A wolf of would be an example of a tertiary consumer. 20. Nitrogen “fixation” refers to the conversion of N2 into ammonia . 21. Primary consumers are animals that eat plants . 22. Hydrogen sulfide is a gas that has a rotten egg smell. 23. The phosphorus cycle has no atmospheric component. 24. Plants store simple sugars as starch . 25. The conversion of nitrates into nitrogen gas is called denitrification . 26. Almost all the sulfur dioxide in the atmosphere is formed by human activities . Reading Three 1. Endemic species are those that occur only where they evolved . 2. Flying squirrels, common inhabitants of temperate hardwood forests, are unusual in that they are the only nocturnal squirrel. 3. Florida scrub jays commonly bury acorns in open sandy areas. 4. Most of Florida’s 8,000 lakes are small . 5. Mortality rate of young alligators is about 80% during the first 2 years of life. 6. The cottonmouth is a common venomous snake in Florida’s wetlands. 7. Florida scrub is a pyrogenic system, which means the plants and animals living there are fire adapted. 8. Marshes are like swamps except they have no trees . 9. Bald eagle and osprey populations in Florida and elsewhere have recovered dramatically since the ban on DDT was implemented. 10. American crocodiles superficially resemble American alligators, but the crocodile can be distinguished by its narrower snout .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
