The overgrowth of algae poses a major problem for coral reefs. Intensive fishing is one factor that contributes to algae overgrowth because it does which of the following?Ask Studybuddy (Login to use)Group of answer choicesAllows more sunlight to be available to algaeInhibits the spread of pathogens in algae coloniesReduces the number of organisms that feed on algaeIncreases the competition between different algae species

When fertilizers run off farmland into streams and ponds, the nitrogen content of the water increases. This can lead to rapid growth of algae in a process called eutrophication. How can this process affect other organisms in the water? Group of answer choicesThe extra nitrogen provides additional food for the other organisms, increasing their population.The water becomes better able to support aerobic organisms.Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.The algae provide food for fishes and other organisms, leading to decreased algae populations.
