Document Summary

Please note that just because something is not on the list is not a reason to ignore it, and just because something is on this list does not mean that you will be tested on it. Know the definitions from the textbook: ex: nitrogen fixation is the main natural input of nitrogen to terrestrial environments. Go one step further and know that n fixing bacteria are necessary for this process, and that they have symbiotic relationships with plants and some animals. This relationship allows an input of nitrogen into the biosphere: know and understand the graphs and pictures. There were a lot of graphs pertaining to trends and population growth. You can logic your way through a lot of the test questions. Just think things through and trust your instincts. Be careful though because questions from the test bank contain true statements that are wrong answers for the question asked.
