    Why are the reefs in the threat?

    • A.

      Climate change

    • B.

      Ocean acidification

    • C.

      Various forms of view

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The reefs are under threat due to climate change, ocean acidification, and various forms of human activity. Climate change leads to rising sea temperatures, which can cause coral bleaching and ultimately kill the reefs. Ocean acidification occurs when carbon dioxide is absorbed by the ocean, leading to a decrease in pH levels that can harm coral reefs. Additionally, various forms of human activity such as pollution, overfishing, and destructive fishing practices can also negatively impact the health and survival of coral reefs.

    How many species can a single dead coral head hold?

    • A.

      150

    • B.

      276

    • C.

      139

    • D.

      Not mentioned

    Correct Answer
    A. 150
    Explanation
    A single dead coral head can hold up to 150 species. Coral reefs are known for their high biodiversity, and even after the death of a coral head, it continues to provide habitat and support for a wide range of organisms. These can include fish, invertebrates, algae, and other marine species. The complex structure of coral heads offers various niches and hiding places, allowing multiple species to coexist and thrive. Therefore, it is estimated that around 150 different species can be found within a single dead coral head.

    What is possibly the most dangerous creature on the reef?

    • A.

      Cone Shells

    • B.

      Lion-Fish

    • C.

      Box-Jelly Fish

    • D.

      Stingray

    Correct Answer
    C. Box-Jelly Fish
    Explanation
    The box jellyfish is possibly the most dangerous creature on the reef because its tentacles contain venomous cells called nematocysts that can cause severe pain, paralysis, and even death in humans. Its venom is potent and can affect the cardiovascular system and nervous system. Box jellyfish are difficult to spot in the water due to their transparent bodies, making them even more dangerous as they can easily come into contact with unsuspecting swimmers. It is important to exercise caution and be aware of the presence of box jellyfish when swimming in reef areas.

    Fringing Reefs are located around the outer edge of the continental islands.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Fringing reefs are coral reefs that directly border the shoreline of continental islands. They are formed close to the coast and are connected to the land. This type of reef is characterized by its shallow and narrow shape, following the coastline. Therefore, it is correct to say that fringing reefs are located around the outer edge of the continental islands.

    How do corals form a hard skeleton?

    • A.

      Secrete calcium carbonate

    • B.

      They dry up and harden

    • C.

      No one is sure of how they form

    • D.

      None of the above

    Correct Answer
    A. Secrete calcium carbonate
    Explanation
    Corals form a hard skeleton by secreting calcium carbonate. Calcium carbonate is a compound that is abundant in the ocean and corals extract it from the water. They then use this calcium carbonate to build their skeletons, which provide them with support and protection. Over time, these skeletons accumulate and form the coral reefs that we see today.

    How many tentacles do hard corals have?

    • A.

      Multiples of 6

      Multiples of 12

    • D.

      Multiples of 9

    Correct Answer
    A. Multiples of 6
    Explanation
    Hard corals, also known as stony corals, are marine invertebrates that typically have multiple tentacles. The number of tentacles varies among different species of hard corals, but they are often found in multiples of 6. This means that the correct answer is "Multiples of 6."
