Type of Ecosystems
There are five types of ecosystems; forest, desert, aquatic, grassland, and tundra. The forest ecosystem has three main biomes. The three main biomes are Tropical rainforests, Temperate forests, and Boreal forests. The desert ecosystem has Hot and Dry deserts, Semi Arid Deserts, Coastal Deserts and Cold Deserts. The aquatic ecosystem has biomes that are grouped into two, Freshwater Biomes (lakes and ponds, rivers and streams, wetlands) and Marine Biomes (oceans, coral reefs and estuaries). The grassland ecosystem is mainly composed of grass, with very few trees and shrubs. It also contains many grazing animals. Last is the tundra, tundras are among Earth's coldest, harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy and rainfall is scant. Tundra lands are snow-covered for much of the year, until summer brings a burst of wildflowers. A decomposer is an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material. A consumer is a person or thing that eats or uses something. What is an ecosystem? An ecosystem is a biological community of interacting organisms and their physical environment. A producer is a person, company, or country that makes, grows, or supplies goods or commodities for sale. A food chain is a hierarchical series of organisms each dependent on the next as a source of food. Biotic means of, relating to, or resulting from living things, especially in their ecological relations. Abiotic is more physical rather than biological; not derived from living organisms. Adaptation is a change or the process of change by which an organism or species becomes better suited to its environment. Biotic factors of a wetland ecosystem include, plants, animals, bacteria, and mainly any living organism in that ecosystem. The examples of animals are reptiles, birds, amphibians, insects, and mammals. Some of the abiotic features of the wetland ecosystem are the climate, water, light, rocks, minerals, and soil. One way down the food web would be algae -> mosquito -> water boatman ->small fish -> large fish ->pelican. Energy enters the food chain and web in the form of sunlight. Wetlands positively affect water quality by filtering the water. They do this by retaining excess nutrients and some pollutants, as well as reducing sediment that would clog waterways. They also offer flood protection by acting as natural sponges that trap and slowly release surface precipitation and flood waters. They also distribute flood waters over the floodplain, controlling floods. Wetlands can also prevent shoreline erosion by holding the soil in place with tree roots, absorbing the energy of waves, and breaking up the flow of streams or rivers currents. This environment also grants a habitat for many animals, by providing food, water, breeding grounds, resting areas, nesting areas and shelter. Other benefits include natural products for our economy, and land to hunt, fish, bird watch or photograph wildlife on.
