      False

    Explanation
    Fishing is not allowed in the Great Barrier Reef. The Great Barrier Reef Marine Park Authority strictly regulates fishing activities in order to protect the delicate ecosystem and biodiversity of the reef. Fishing is only permitted in certain designated areas outside of the marine park, and even then, there are strict regulations and limits on what can be caught. Therefore, the statement that fishing is allowed in the Great Barrier Reef is false.

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement "The reef is made up of living organisms" is true. Reefs are formed by the accumulation and growth of coral polyps, which are tiny marine animals. These polyps secrete calcium carbonate to build their hard exoskeletons, which eventually form the structure of the reef. Additionally, reefs provide habitats for a wide variety of other living organisms, such as fish, sponges, and algae. Therefore, it can be concluded that reefs are indeed made up of living organisms.
