46. How does the destructlon of caral reefa and mangrove foreste contribute to spacias extinctlon? A. Amount of dissolved oxygen decreases. B. Fish predators become massive in number. C. Breeding grounds and nurseries of marine species are destroyed. D. The oceans and seas become contaminated with heavy metals and other pollutants. | 47. Which of the following best explains eutrophication? A. Forests are cleared to make the land available for other purposes B. People collect, capture, or harvest marine organisms such as coral reefs, fish, sea turtles, and others in a large quantity C. The weakening or death of trees caused by Nitrogen Oxides (NOx) and Sulfur dioxide (SO2) that reacts with water, oxygen, and other chemicals in the atmosphere. D. An increase of organic nutrients brought about by the chemicals and garbage thrown into the bodies of water which stimulates the growth of algae and in turn, lessens the available oxygen for 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 and consequently becomes extinct. B. Amphibian populations have been on the decline worldwide caused by fungal infection of their skin which interferes with osmoregulation C. When a large predator, the Nile perch, was introduced into Lake Victoria, it caused the extinction of half of the species of fish endemic in it. D. When bacteria in a lake increase in number due to continuou's decomposition of dead organisms, dissolved oxygen declines, killing all the fishes in it.
