Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
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?
A
Allows more sunlight to be available to algae
B
Inhibits the spread of pathogens in algae colonies
C
Reduces the number of organisms that feed on algae
D
Increases the competition between different algae species
Explanation: 

Detailed explanation-1: -The overgrowth of algae poses a major problem for coral reefs. Intensive fishing is one factor that contributes to algae overgrowth because it reduce the number of organisms that feed on algae. The correct option is C.

Detailed explanation-2: -The researchers theorized that when increased levels of algae produce meals for microbes, there are also higher levels of potentially harmful microbes throughout the reef ecosystem. These microbes then endanger corals by depleting oxygen from the environment or by introducing diseases.

Detailed explanation-3: -Which of the following is a possible explanation that relates the intensive fishing to the overgrowth of algae? Allows more sunlight to be available to algae increasing their growth.

Detailed explanation-4: -Invasive algae can quickly invade and take over coral-dominated habitats. They can overgrow and kill coral by smothering, shading, and abrasion, and can cause reduction in biodiversity and coral cover.

Detailed explanation-5: -The ability of an ecosystem to remain at equilibrium in spite of disturbances is called resistance. How readily an ecosystem returns to equilibrium after being disturbed is called resilience.
