  • The Forest Ecosystems the ecosystems in which an abundance of flora, or plants, is seen so they have a big number of organisms which live in relatively small space. So, in forest ecosystems the density of living organisms is quite high. A small change in this ecosystem could affect the whole balance, effectively bringing down the whole ecosystem.The Desert Ecosystem Desert ecosystems are located in regions that receive an annual rainfall less than 25. Due to the extremely high temperature, low water availability and intense sunlight, fauna and flora are scarce and poorly developed. The vegetation is mainly shrubs, bushes, few grasses and rare trees. The stems and leaves of the plants are modified in order to conserve water as much as possible.The Grassland Ecosystem Grasslands are located in both the tropical and temperate regions of the world though the ecosystems vary slightly. The area mainly comprises grasses with a little number of trees and shrubs. The main vegetation includes grasses, plants and legumes that belong to the composite family. A lot of grazing animals, insectivores and herbivores inhabit the grasslands. The two main kinds of grasslands ecosystems are Savanna and Prairies.The Mountain Ecosystem Mountain land provides a scattered and diverse array of habitats where a large number of animals and plants can be found. At the higher altitudes, the harsh environmental conditions normally prevail, and only the treeless alpine vegetation can survive. Lower slopes are commonly covered with coniferous forests.The Aquatic Ecosystems The aquatic ecosystem is the ecosystem found in a body of water. It encompasses aquatic flora, fauna and water properties, as well. There are two main types of aquatic ecosystem - Marine and Freshwater. Marine Ecosystems are the biggest ecosystems, which cover around 71% of Earth's surface and contain 97% of out planet's water. Water in Marine Ecosystems features in high amounts minerals and salts dissolved in them. Freshwater Ecosystems on the contrary to the Marine ecosystems, the freshwater ecosystem covers only 0.8% of Earth's surface and contains 0.009% of the total water.


Decomposer is an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material. A consumer is something that produces it's own food. An ecosystem is a biological community of interacting organisms and their physical environment. A producer is an organism or plant that is able to take energy from the sun and make its own food. A food chain is a series of organisms each dependent on the next as a food source. A biotic is of or relating toor resulting for living things especially in their ecological relations. Abiotic is physical rather than biological, not derived from living organisms. Adaptation is a change or the process of change by which an organism or species become better suited to its environment.

Examples of biotic and abiotic factors in a wetland ecosystem

Some examples of Biotic factors in a wetland ecosystem are turtlehead flowers, water, trees, butterflires, competition, bacteria, carrying capacity, plaintain, ash, and the false foxglove.

Some examples of Aiotic factors in a wetland ecosystem are sunlight, air, climate, soil, water, rocks, and temperature.

Energy enters an ecosystem food chain in the form of sunlight, and leaves the food chain in the form of heat.

The arrows in the food chain represent how food is passed through the food chain.

they find other things of food , then start eating each other or they die from not being able to feed themselves.

wetlands provide values that no other ecosystem can, including natural water quality improvement, flood protection, shoreline erosion control, opportunities for recreation and aesthetic appreciation, and natural products for our use at no cost.

Wetlands have important filtering capabilities for intercepting surface- water runoff from higher dry land before the runoff reaches open water. As the runoff water passes through, the wetlands retain excess nutrients and some pollutants, and reduce sediment that would clog waterways and affect fish and amphibian egg development.

The ability of wetlands to control erosion is so valuable that some states are restoring wetlands in coastal areas to buffer the storm surges from hurricanes and tropical storms. Wetlands at the margins of lakes, rivers, bays, and the ocean protect shorelines and stream banks against erosion.

For many animals and plants, like wood ducks, muskrat, cattails, and swamp rose, inland wetlands are the only places they can live.
