Question

1. what is camouflage, and how do marine organisms use it?
2. name one example of a marine organism that uses bioluminescence.
3. why is biodiversity important in marine ecosystems?
4. what is the coral triangle, and why is it significant?
5. list two threats to marine biodiversity mentioned in the text.
6. how does migration help marine animals survive?
7. what role does habitat complexity play in marine ecosystems?
8. give an example of a conservation effort mentioned in the reading.
9. what happens to coral reefs during coral bleaching?
10. how many species of reef - building corals are found in the coral triangle?

Explanation:

1. Camouflage is a survival - strategy where organisms blend into their environment. Marine organisms use it to avoid predators or catch prey. For example, some fish change color to match the sea - floor.
2. The anglerfish is an example of a marine organism that uses bioluminescence to attract prey in the dark depths of the ocean.
3. Biodiversity is important in marine ecosystems as it helps maintain ecological balance, provides food sources, and contributes to the resilience of the ecosystem against environmental changes.
4. The Coral Triangle is a region in the western Pacific Ocean known for its high marine biodiversity, especially in coral species. It is significant as it is a nursery for many marine species and supports local livelihoods.
5. Two threats to marine biodiversity are overfishing, which depletes fish populations, and ocean acidification, which harms shell - building organisms like corals.
6. Migration helps marine animals find food, escape harsh environmental conditions, and reproduce in more favorable areas.
7. Habitat complexity in marine ecosystems provides shelter, breeding grounds, and food sources for a wide variety of species, increasing biodiversity.
8. One conservation effort could be the establishment of marine protected areas to safeguard habitats and species.
9. During coral bleaching, corals expel the symbiotic algae living in their tissues, turning white. This can lead to coral death if the stressor is not removed.
10. There are over 600 species of reef - building corals found in the Coral Triangle.

Answer:

1. Camouflage is a way for organisms to blend into their surroundings. Marine organisms use it for protection from predators or to ambush prey.
2. Anglerfish
3. It maintains ecological balance, provides food, and enhances ecosystem resilience.
4. It's a region in the western Pacific with high marine biodiversity, especially corals. It's significant as a species nursery and for local livelihoods.
5. Overfishing, ocean acidification
6. It helps them find food, escape bad conditions, and reproduce.
7. It provides shelter, breeding sites, and food, increasing biodiversity.
8. Establishment of marine protected areas
9. Corals expel symbiotic algae, turn white, and may die.
10. Over 600 species
