![]() Lakes and ponds are divided into three different "zones" which are usually determined by depth and and its distance from the shoreline. There is not that much diversity in species since ponds and lakes are often isolated from one another and from other water sources like rivers and oceans. Many ponds are seasonal, just lasting a couple of months, such as sessile pools, while lakes last many years. Lakes evolved during the Pleistocene Ice Age. Scattered throughout the earth, many of the first These regions range in size of just a few square meters to thousands The following sections will talk about the different characteristics of each of these three freshwater zones. ![]() There are different types of freshwater regions: ponds and lakes, streams and rivers, and wetlands. Other characteristics of freshwater regions are that the plants and animals in the region are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e, ocean). There is a low salt concentration, usually less than 1%. Obviously, aquatic areas tend to be a little humid and the air temperature slightly on the cool side, even though the temperature of the water can vary widely.Īs you might guess from the name, the water is fresh, meaning that The only thing that links all the areas together is that there is water. The aquatic biome can be broken down into two basic areas, freshwater (i.e, ponds and rivers) and marine (i.e, oceans and estuaries). Today, without water, no life would be able to sustain itself and the earth would be a barren, desert-like place. This is also where life basically started billions of years ago when amino acids started to form together in the water. Aquatic areas house numerous species of animals, large and small, and plants. Being the largest part of the biosphere, it covers nearly 75% of the Earth's surface.
