Which of the following factors is used to distinguish the two main aquatic biomes?

1)number of producers
2)strength of water currents
3)quality of dissolved oxygen
4)salt levels

I think #4
Thank you.

I believe you are correct.

Thanks guys

Yes, you are correct. The factor that is used to distinguish the two main aquatic biomes is the salt levels, so the correct answer is number 4.

To arrive at this conclusion, you need to have knowledge of the characteristics of the two main aquatic biomes: freshwater and marine. Freshwater biomes have low salt levels or are completely devoid of salt, while marine biomes have high salt levels due to the presence of sodium chloride. The difference in salt levels is responsible for the distinct characteristics, such as the kinds of organisms that can survive in each biome.

Therefore, by understanding this concept, you can determine that the factor used to distinguish the two main aquatic biomes is the salt levels.
