What is freshwater biome for kids



A lake at Acadia National Park, Maine.
  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). There are different types of freshwater regions:

Ponds and lakes
These regions range in size from just a few square meters to thousands of square kilometers. Scattered throughout the earth, several are remnants from the Pleistocene glaciation. Many ponds are seasonal, lasting just a couple of months (such as sessile pools) while lakes may exist for hundreds of years or more. Ponds and lakes may have limited species diversity since they are often isolated from one another and from other water sources like rivers and oceans. Lakes and ponds are divided into three different “zones” which are usually determined by depth and distance from the shoreline.

The topmost zone near the shore of a lake or pond is the littoral zone . This zone is the warmest since it is shallow and can absorb more of the Sun's heat. It sustains a fairly diverse community, which can include several species of algae (like diatoms), rooted and floating aquatic plants, grazing snails, clams, insects, crustaceans, fishes, and amphibians. In the case of the insects, such as dragonflies and midges, only the egg and larvae stages are found in this zone. The vegetation and animals living in the littoral zone are food for other creatures such as turtles, snakes, and ducks.

Biomes . A biome is a large, distinctive complex of plant communities created and maintained by climate. How many biomes are there?

Biomes . Lots of color photographs of Terrestrial Biomes, Un-Biome: Polar / Alpine, Tundra, Boreal Forest (Taiga), Temperate Forest, Grasslands (Steppes), Woodland (Chaparral), Desert, Tropical Deciduous Forest and Savannah, Tropical Rain Forest, and Temperate Rain Forest.

Biomes . Web pages developed by some 70 Grade 9 students at Thurston High School in Springfield, Oregon. Each page deals with one biome under these categories: Animals, Plants, Climate, and Health Issues.

Freshwater biomes are large communities of plants and animals centered around waters with less than 1% salt concentration. They are very important to survival on Earth. Types of freshwater biomes include ponds, lakes, streams, rivers, and even some wetlands. (Wetlands are not always considered freshwater biomes because they usually have too high of a salt content.)

Lakes and ponds are considered still water since they do not move very fast. Rivers and streams move water from one area to another and are known as moving waters. Both still waters and moving waters offer a home to many different types of plants and animals. Many of these organisms are structured to live in a specific type of freshwater habitat. For example, some plants thrive in the nice calm waters of a lake but don't survive in rivers and streams, unless they have a specific structure or can hold onto objects like rocks.
