An increase of organic nutrients brought about by the chemicals and garbage thrown into thebodies of water which stimulates the growth of algae and in turn, lessens the available oxygenfor other aquatic animals.48. Which illustrates how the introduction of new species may lead to extinction?A. When a prey species becomes extinct; its predator loses its food source andconsequently becomes extinct.B.
