Why does coral grow best in moving water?Watch
Suggest how the mutualistic relationship between the small animals (within coral that has a hard calcium shell) and the algae inside them is of benefit to both species. (2 marks)
Give one reason why coral that survives higher sea temperatures is under increased threat from predators (1 mark)
The animals may provide the coral with nutrients, while the algae provide oxygen via photosynthesis.
I'm guessing that the coral in higher temperature waters will be more vulnerable to predation because more of the other aquatic plants will have died, so there is less variety of food for predators, making corals more vulnerable as the predators have fewer/no alternative food sources.
Suggest how scientists are able to find the percentage of coral that has died in a section of the reef. (3 marks)
Suggest what recommendations should be included in the sustainability plan for the coral reef (3 marks)
