Types of Ecosystems

The five different types of ecosystems are tropical rain forest, savannas, tundra, ocean, and desert. Tropical rain forests will vary little in temperature, they will have many different kinds of species, and will receive an average of 250 cm of precipitaion per year. Savannas are very wide open spaces with few trees and will receive about 90-150 cm of of precipitation. In a tundra the ground will always remain frozen, it is a very wide open space with few plants, and it will receive about 25 cm of precipitation per year. There are three different kinds of ocean ecosystems; shallow ocean waters, deep ocean water, and deep ocean surface. It is based upon the photosynthesis plankton for the food chain. A desert ecosystem is very dry and with very little amounts of vegetation or precipitation.


A decomposer is an organism that will decompose organic material that is found in the ground.

If an organism, most often an animal, will feed on either plants or other animals then it is a consumer.

An ecosystem is a system of interacting organisms that interacts with the surrounding environment and is normally very complex.

Most plants are producers that will create their own food through a process called photosynthesis.

A food chain is a system of interacting organisms where larger organisms feed upon smaller organisms and works as a chain where the sun is the main energy source.

A biotic ecosystem is a system of organisms that is relating to living organisms like plants or animals.

There are not many places on Earth that are abiotic which means that there is areas that are characterized by the absence of life or any living organisms.

Animals like chameleons have an adaptation where they skin color will change to blend with is surroundings and many other animals will have adaptations to survive in a habitat.

Factors of a Wetland Ecosystem

Biotic factors of a wetland ecosystem includes, 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.

Wetland Ecosystem Food Chain

In a wetland ecosystem the producer can be algae which is consumed by mosquitos. This is then consumed by a water boatman and then that is consumed by a diving beetle. This is then consumed by a dragonfly and later consumed by a frog. The frog is then consumed by the top predator of a pelican.

Energy Source

Energy enters into this ecosystem by solar energy.  This solar energy comes from the sun and the sun will help the producers to be able to do photosynthesis. Consumers will then consume the producers to consume their energy. The decomposers will then consume the consumer's energy. Producers will then consume some energy from these decomposers and the cycle continues. Therefore, all of this energy comes from the sun.

Arrows in an Ecosystem

The arrows in an ecosystem represent where energy is moving to. This shows that when an arrow is pointing to something it is consuming the energy from where the arrow is coming from. Therefore, when an arrow is pointing to something, it is consuming what the arrow is coming from.

Elimination of an element

If something were to be eliminated from this food chain then there would be very drastic effects. The consumer that gains energy from that element will most likely not receive enough energy that they will either die or have to look for another energy source. This will cause many consumers that consume this source of energy to die of disease and move to a different habitat to survive.

Positive Effects of Wetlands

Wetlands will make water quality better since the wetland will retain excess pollutants and nutrients that pass through the wetland by the runoff from higher ground. This will reduce the amount of sediment that passes through the wetland and make the water quality better in the water past the wetland.

Flood Protection

The wetland will act as a sponge that will slow the speed of the water and stop floods. Trees will also slow the speed of water and slowly distribute this water over areas so that those areas will not be flooded.

Protection from Shore Erosion

Wetlands will protect the shoreline from erosion since the shore will be held together from roots in a wetland. Also, wetland will resist the energy of waves and break up the current of rivers.

Habitat for Wildlife

Wetlands will provide habitat for wildlife because it is a very common breeding ground for fish and it is also where fish will raise their young. It also provides much food and shelter for many different species for their survival. Many other species will use wetlands as food and resting and if they were not a wetland there, then they would most likely go extinct. For some plants and animals, wetlands are the only place that they can live.


Some other benefits of wetlands are that they offer many natural products such as plants, hunting and medicine. There are many fishing products that are harvested from wetlands for a very large profit. It will also be used for hunting, fishing, bird watching, and photography.
