Answer 2

## Step1The first question is about the symbiotic relationship between stony marine corals and zooxanthellae. The correct answer is mutualistic, as both organisms benefit from their relationship.## Step2The second question asks about the ocean zone that makes up the greatest percentage of the open ocean. The correct answer is the aphotic zone, which is the deepest part of the ocean where no sunlight penetrates.## Step3The third question is about the wavelengths of light that can penetrate deepest into the ocean. The correct answer is blue, as it is the least absorbed by water and can penetrate the deepest.## Step4The fourth question asks about the disadvantages of aquaculture. The correct answer is that it can lead to the spread of diseases among fish.## Step5The fifth question is about the methods used to redistribute oil after an oil spill. The correct answer is dispersants, as they are used to break up the oil into smaller droplets, which can then be more easily removed.## Step6The sixth question is about the type of pollution caused by fertilizer runoff into a local stream. The correct answer is nonpoint-source nutrient pollution, as it is caused by runoff from agricultural fields and other non-specific sources.
