Answer:
Component 4B
1. Common biotic features of a coral reef include fish, sea turtles, sea stars, crabs, and other marine life. Abiotic features include sand, rocks, and sunlight.
2. Common predators that prey on coral include fish, sea stars, crabs, and other marine life.
3. Coral is a living thing because it is composed of living organisms called polyps. These polyps are responsible for building the coral reef by secreting calcium carbonate, which forms the hard skeleton of the coral. The polyps also contain symbiotic algae, which provide the coral with energy and nutrients.
Component 4C
Answer:
Q1. Another coral reef besides the Australian Great Barrier Reef is the Mesoamerican Reef, located in the Caribbean Sea.
Q2. Two abiotic factors whose change would affect the life of the corals are water temperature and salinity.
Q3. A change in water temperature can cause coral bleaching, which is when the coral expels the symbiotic algae living in its tissues, leaving it vulnerable to disease and death. A change in salinity can also cause coral bleaching, as well as disrupt the coral's ability to absorb nutrients from the water.
