The aquatic biome has two main basic regions, freshwater and marine. The limnetic zone is well-lighted (like the littoral zone) and is dominated by plankton, both phytoplankton and zooplankton. Freshwater biomes differ from marine biomes. The aquatic regions house numerous species of animals and plants, either big or large. Aquatic ecosystems are any environment in which organisms interact with the chemical and physical features of the aquatic environment. Aquatic ecosystems are generally divided into two types --the marine ecosystem and the freshwater ecosystem. An aquatic biome is one of the five main biomes of the earth. 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. The first life on our planet evolved in ancient waters about 3.5 billion years ago. Aquatic ecosystems are also used for human recreation, and are very important to the tourism industry, especially in coastal regions. These various roles and human benefits are referred to as ecosystem services. Even if the water in a pond or other body of water is perfectly clear (there are no … In fact it is the water that covers almost 75% of the Earth’s surface and makes up the largest part of the biosphere. Plankton are small organisms that play a crucial role in the food chain. Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. They also include wetlands. A variety of freshwater fish also occupy this zone. 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. 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%. For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife. 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. Humans rely on freshwater biomes to provide aquatic resources for drinking water, crop irrigation, sanitation, and industry. Water covers nearly 75 percent of the earth's surface, in the form of oceans, lakes, rivers, etc. Aquatic ecosystems perform many important environmental functions.

The aquatic biome is the largest of all the world's biomes—it occupies about 75 percent of the Earth's surface area. The aquatic medium—water— has different physical and chemical properties than air, however. Aquatic ecosystems are the largest of all ecosystems and cover almost 71% of the Earth's surface. The aquatic biome is definitely the largest biome out there. As opposed to terrestrial biomes, the different types of aquatic ecosystems stand out because their biotope, a portion of a habitat, consists of a large body of water. The largest water ecosystem is the marine ecosystem. Freshwater biomes include lakes and ponds (standing water) as well as rivers and streams (flowing water). Marine life, however, has to be adapted to living in a habitat with a high concentration of salt.
