Linda Tran Visual Vocabulary
Cultural Eutrophication • An increase in fertility in a body of water, the result of anthropogenic inputs of nutrients • Chesapeake Bay experiences an increase in fertility due leached agricultural lands during rainy periods
Curie • A unit of measure for radiation; 1 curie= 37 billion decays per second • If a material has a radioactivity level of 100 curies and has a half-life of 50 years, the radioactivity level in 200 years will be 4 half-lives
Dam • A barrier that runs across a river or stream to control the flow of water • Damns are used for human consumption, generation of electricity, flood control, and recreation
Dead Zone • In a body of water, an area with extremely low oxygen concentration and very little life • When raw sewage is dumped directly into bodies of water, subsequent decomposition of microbes can consume nearly all the oxygen and create a dead zone
Decomposers • Fungi or bacteria that recycle nutrients from dead tissues and wastes back into an ecosystem • Without decomposers, detritvores, and scavengers there would be no way of recycling organic matter and energy and thus would create a world filled with dead plants and animals
Deductive Reasoning • The process of applying a general statement to a specific fact or situation • For example • GS: Air pollution kills tree • One dead tree does not mean that it was killed by air pollution. There could be other causes such as poor sunlight
Demographer • A scientist in the field of demography • Analyze specific data such as birth rates, death rates, and migration rates
Demography • The study of human populations and population trends • Demographers use age structure diagrams to determine the state of the country because developing and developed countries have specific population trends
Density Dependent Factor • A factor that influences an individual’s probability of survival and reproduction in a manner that depends on the size of the population • Limited food supply is an example of a D-D factor because a smaller population requires less total food
