module13REVIEW

In this module, we have learned that aquatic biomes are characterized by physical features such as salinity, depth, and water flow. Freshwater biomes include streams and rivers, which have flowing water, and lakes, ponds, and wetlands, which have standing water. Marine biomes contain salt water and include salt marshes, mangrove swamps, intertidal zones, coral reefs, and the open ocean. Differences in water flow, depth, and salinity help us understand why different species of producers and consumers, including commercially important species of fish and shellfish, live in different aquatic regions of the world.
