Answer:
A coral reef is a reef-shaped structure in the sea, formed by anemones and which over time becomes large enough to have a significant ecological and physical impact on its environment. These are the largest structures built from living organisms in the world. Coral reefs are complex marine ecosystems. They are a biotope (area of life) of a biocenosis (community of living beings) consisting of plants and animals, for example worms, shellfish, sponges, thorns and crustaceans. Coral reefs play a significant role as “breeding grounds” for the offspring of fish inhabiting the high seas.

<span>The best answer is (d) water from snowmelts. The American Southwest has many mountains that catch moist air moving westward (from the Pacific) that falls as snow during the winter. The snow melts gradually during the spring and summer when there is little precipitation. The melted snow runs off the mountains into rivers and streams that can be tapped by irrigation pumps. The snowmelt also sinks into the ground, replenishing underground aquifers that can be tapped by wells in the valleys where farming takes place.</span>
