Ans.
The biodiversity of a coral reef ecosystem will be decrease if there is a decrease in coral reef population as most if the marine organisms, such as microbes, sea urchins, plankton, fishes, seahorses, along with larger animals, such as sea turtles, directly or indirectly depend on coral reefs. As seaweeds act as competitors of corals, overgrowth of seaweed population would decrease population of corals.
This will lead to a disturbance in coral reef ecosystem and decrease the ecosystem's biodiversity. Thus, the correct answer is 'option B). the overgrowth of seaweed would prevent light from reaching the reef.'
In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer onesI just learned about this in our rocks and minerals unit for science,
