Detailed explanation-1: -An ecosystem characterized by low-salt content, making a suitable environment for various plants and animals is known as a freshwater ecosystem. Freshwater resources vary in terms of size from very small to large.

Detailed explanation-2: -The aquatic biome is divided into freshwater and marine regions. Freshwater regions, such as lakes and rivers, have a low salt concentration.

Detailed explanation-3: -What are the 8 aquatic biomes? The 8 aquatic biomes are lakes and ponds, rivers and seas, oceans, estuaries, coral reefs, wetlands, mangroves, and intertidal zones.

Detailed explanation-4: -Estuaries: Where the Ocean Meets Fresh Water Estuaries form protected areas where many of the young offspring of crustaceans, mollusks, and fish begin their lives. Salinity is a very important factor that influences the organisms and the adaptations of the organisms found in estuaries.

Detailed explanation-5: -The saltiest locations in the ocean are the regions where evaporation is highest or in large bodies of water where there is no outlet into the ocean. The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40‰) due to very high evaporation and little fresh water inflow.
