Ecosystems

By: Calvin Whybrew #EcoFlow

                         There are many types of ecosystems. Below are five examples.

     One type of ecosystem is the freshwater ecosystem. This makes up about 1.8% of the Earth's surface. This supports many species of life including fish, insects and plants. The base of the ecosystem is freshwater plankton and the sun. Another type is the ocean ecosystem. 75% of the Earth is made up of oceans, and 40% of all photosynthesis occurs in oceans. Photosynthetic plankton is the base of this ecosystem. Another is the forest ecosystem. It is abundant in plants, and has a large number of organisms living in a relatively small space. There is also the desert ecosystem. It is makes up 17% of the Earth and is scarce in plants and animals. One last example is the grassland ecosystem. The area is mainly composed of grass, with very few trees and shrubs. It also contains many grazing animals.

                                        Ecosystem words in sentences

A decomposer is an organism that breaks down dead organisms.

The consumer ate another organism in the food chain.

That ecosystem is made up of interacting organisms and their environment.

The producer makes its own food through photosynthesis.  It also serves as food for other organisms.

A food chain is a series of organisms that depend on the next as a source of food.

An ecosystem is very much biotic in nature.

The factory was abiotic, it wasn't created from living things.

The organism's adaptation made it better suited to its environment.

                                           Wetland Ecosystem Biotic and Abiotic Features

     In the wetland, there are amphibians, reptiles, birds, insects, mammals, mangroves, water lilies, cattails, tamarack, black spruce, cypress, and gum plants. These are examples the biotic factors, which include plants, animals, bacteria, and other living organisms.  The abiotic factors in wetlands are the climate, light, rocks, water, minerals, soil and other factors found in all biomes.  

Wetland Ecosystem Food Chain

     Above is what a wetland ecosystem food chain might look like, and below is what a wetland ecosystem food web might look like.  If one of the above elements in the food chain were to be eliminated by disease or habitat loss, the organisms to the right of that organism would most likely die.

     One way down the food web would be algae -> mosquito -> water boatman ->small fish -> large fish ->pelican.  The arrows above represent the flow of energy in the web/chain.  The algae is the producer, the mosquito is the primary consumer, the water boatman is the secondary consumer, and the small fish is the tertiary consumer.  The large fish is the quarternary consumer, and the pelican is the top predator.

Energy enters the food chain and web in the form of sunlight.

Energy Flow Through an Ecosystem

    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.

Cellular Respiration

    All cells of living things carry out cellular respiration continuously.  Producers carry out photosynthesis, but producers and consumers both carry out cellular respiration.
