What is water clarity and why is it important?

Water clarity is a measure of how far down light can penetrate through the water. The clearer the water is the farther light can go down. This is important because with water clarity we can find out how much living things that part of the water can support. Clearer water allows light to reach farther down, which can allow aquatic plants to grow deeper in the water.

answer; i believe that the correct answer is (c) explore the outer planets; / plz check good luck

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
