Ques:Answer the following question given this paragraph: Freshwater biomes are defined by their low salt concentration, usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration, such as the ocean. There are different types of freshwater biomes: ponds and lakes ( Figure below ), streams and rivers, and wetlands. Ponds and lakes range in size from just a few square meters to thousands of square kilometers. Streams and rivers are bodies of flowing water moving in one direction. They can be found everywhere.

Wetlands are areas of standing water that support aquatic plants. Wetlands include marshes, swamps, and bogs. Q: What are fresh water biomes defined by? Choices: - high salt content - moving water - animal species - low salt concentration A:

Ans:low salt concentration
