Textbook Question
Chapter 57, Problem 3A
If a pesticide is harmless at low concentrations (such as DDT) and used properly. how can it become a threat to nontargct organisms?
a. Because after exposure to DDT. some species develop allergic reactions even at low levels of exposure
b. Because DDT molecules can combine so that their concentration increases through time
c Because the concentration of chemicals such as DDT is increasingly concentrated at higher trophic levels
d. Because global warming and exposure to UV-B radiation renders molecules such as DDT increasingly potent

Though the Everglades are protected, pythons as predators can not be easily controlled. What can be concluded about the effect of the python population on the biodiversity of the Everglades? A. Since the Everglades are protected, python control is limited under laws that protect species in the Everglades. B. Since the python population is growing, it will eventually become a native species and will increase biodiversity. C. Since pythons prey on many species in the Everglades, resources will be more available for surviving species and fewer will be considered endangered. D. Since pythons have no predators, they are responsible for decreasing mammal population and are a greater threat to biodiversity.arrow_forward
