Solution
Intensive fishing contributes to algae overgrowth on coral reefs by reducing the number of organisms that feed on algae. Here's how:
-
Many fish species, especially herbivorous ones, feed on algae. They play a crucial role in maintaining the balance of the ecosystem by controlling the algae population.
-
When intensive fishing occurs, the population of these algae-eating fish decreases. This is because many of them are caught and removed from the ecosystem.
-
With fewer fish to eat them, the algae population can grow unchecked. This leads to an overgrowth of algae.
-
The overgrowth of algae can smother coral reefs, blocking sunlight and preventing the corals from carrying out photosynthesis. This can lead to the death of the corals and the degradation of the entire reef ecosystem.
So, intensive fishing indirectly contributes to algae overgrowth by reducing the population of algae-eating organisms.

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.
