Others, such as lakes, ponds, and wetlands, have water that stays put for the most part. Freshwater ecosystems such as lakes, ponds, rivers, streams and wetlands are estimated to cover 15 per cent of the world's continental surface area. The land surface discipline includes research into areas such as shrinking forests, warming land, and eroding soils. They also help the domesticated and Terrestrial ecosystem to survive and keep these kind of ecosystem alive in nature. Freshwater ecosystems: characteristics, flora, fauna The freshwater ecosystems they are one of the types of aquatic ecosystems that exist on planet Earth. They can be contrasted with marine ecosystems, which have a larger salt content. Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater. Freshwater ecosystems connect headwaters with oceans, land with water and people with the resources they need to thrive, Abell said. Under the limnetic zone is and are that is much colder and denser region, known as the profundal zone. Aquatic ecosystems are globally significant sources of the greenhouse gas methane to the atmosphere. Whereas marine habitats include oceans, intertidal zone, reefs, seabed and so on. Freshwater ecosystems are vital for all living organisms as they possess rich natural resources. Less than three percent of our planet's water is freshwater, and less than half of that is available as a liquid; the rest is locked away as ice in polar caps and glaciers. Let us look at these in detail. There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes ), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time). Pollution, global warming, and climate change are some of the reasons that put freshwater biomes into danger.
