Compare and contrast two biomes

    One biome is the freshwater biome. Freshwater is defined as having a low salt concentration usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e., ocean). These ponds and lakes range in size from just a few square meters to thousands of square kilometers. Another biome is the desert biome. Deserts cover about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Most deserts have a considerable amount of specialized vegetation, as well as specialized vertebrate and invertebrate animals. Soils often have abundant nutrients because they need only water to become very productive and have little or no organic matter. Disturbances are common in the form of occasional fires or cold weather, and sudden, infrequent, but intense rains that cause flooding.The difference between freshwater and desert biome is that the desert hardly has any water while the freshwater biome is covered with water.
