Aquatic ecosystems perform many important environmental functions. Aquatic biomes. Freshwater biomes include lakes and ponds (standing water) as well as rivers and streams (flowing water). In fact it is the water that covers almost 75% of the Earth’s surface and makes up the largest part of the biosphere. Aquatic ecosystems are also used for human recreation, and are very important to the tourism industry, especially in coastal regions.

Aquatic Biome • it makes up the largest part of the biosphere • There are two main types of Aquatic Biomes: 1.Freshwater 2. The aquatic biome provides a vast array of habitats that, in turn, support a staggering diversity of species. Plankton are small organisms that play a crucial role in the food chain. The aquatic medium—water— has different physical and chemical properties than air, however. A freshwater biome is a large community of flora and fauna (plants and animals) that live in water bodies with low salt content, usually less than 1%. The largest water ecosystem is the marine ecosystem. They also include wetlands. Marine life, however, has to be adapted to living in a habitat with a high concentration of salt.

The aquatic biome has two main basic regions, freshwater and marine. This biome is usually divided into two categories: freshwater and marine.Typically, freshwater habitats are less than 1 percent salt. Examples of freshwater biomes include lakes, ponds, streams, rivers and even some wetlands. Even if the water in a pond or other body of water is perfectly clear (there are no … Humans rely on freshwater biomes to provide aquatic resources for drinking water, crop irrigation, sanitation, and industry. The limnetic zone is well-lighted (like the littoral zone) and is dominated by plankton, both phytoplankton and zooplankton. The aquatic biome is the largest of all the biomes, covering about 75 percent of Earth’s surface. Without aquatic plankton, there would be few living organisms in the world, and certainly no humans. Aquatic ecosystems are generally divided into two types --the marine ecosystem and the freshwater ecosystem. Aquatic ecosystems are any environment in which organisms interact with the chemical and physical features of the aquatic environment. A variety of freshwater fish also occupy this zone. Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors.
