Question

How does a marine biome differ from a freshwater biome?

• A. Amount of sunlight that strikes the surface of the water
• B. Amount of salt dissolved in the water
• C. Amount of algae that is found in the water
• D. The temperature of the water

Answer 1

Answer: (B)

Amount of salt dissolved in the water

Is the correct answer because a marine biome is contrasted to a freshwater biome by the amount of dissolved salt found in the water. In marine biomes there is much more dissolved salt found in the water than in freshwater biomes. (A) is not correct because the amount of sunlight that strikes a given surface area of water will vary in both marine and freshwater biomes. (C) is not correct because the amount of algae found in the water can be both high and low in freshwater and marine biomes. (D) is not correct because the temperature of the water can be both high and low in freshwater and marine biomes.
