River+Ecosystem+by+FBiB

=Introduction= Hi my name is “Facebookisbetter” and I go to the Amigos School. I am doing this Wiki because I feel that not many people know enough about the Charles River, even if they think they do. This is describing both the Biotic (Living) Consumers, (Herbivores, Omnivores and Carnivores) Producers (Plants) And Decomposers, and the Abiotic (Non-Living) components and how they affect the Biotic Life. We went to the Charles River two times. Once on Friday, October 3rd, and again on Friday October 10th. Only the second time their was a very drastic alteration by a certain consumer, one we all know and love. (You’re probably thinking “Dogs?”) But no, it is Mankind.

=Location= As our school is rather close to the Charles River we took a nice walk on October 3rd and 10th. We tested pH, Turbidity, DO and temperature. According to the World Water Monitoring Day (WWMD) Test Kit the pH is 7.0. Also the Turbidity is 20 JTU and the DO is 4ppm. Using the World Water Monitoring Day Test Thermometer the temperature was 21º Celsius. An article I wrote about the Charles River has been posted on the WWMD website and can be viewed for your viewing pleasure [|Here.] It is under Cambridge, Charles River.

=Biotic= A river isn’t the first place that comes to mind when you say Biotic (Living) organisms. But surprisingly enough, there was enough to make a whole energy pyramid and food web. Here I will describe three producers (plants) consumers (animals) and decomposers. One consumer was plankton. Technically, it is a primary consumer, secondary consumer, tertiary consumer, and a producer. (Primary=herbivore, secondary= omnivore, tertiary=carnivore) Another was the mass of Canadian Geese. It was pretty messy. (Meaning you should watch your step) The ultimate consumer was birds. That is pretty general, because birds can be primary, secondary, or tertiary. The specific types of birds were seagulls (kind of funny we found them at the River), Cormorants, and as above stated, Canadian Geese. Three producers are Lilies, Clovers, and Grass. Three Decomposers (The definition of Decomposer can be found Here) we found are Bracket Fungus, Bacteria, and Lichen. The function of an energy pyramid is that the top eats the second-to-top, which eats the third-to-top, so on so forth. Without the bottom the top can’t survive because it has no food. My food web can be found Here and my energy pyramid Here. Click Here to se my web in spanish.

=Summary= You’d think that with a river I’ve walked on 500 times that one time this year wouldn’t make a difference. But of course you would be wrong. The first thing that I learned is that it’s not as dirty as you might think. The pH is 7.0, which is as good as it gets. Second is that an entire energy pyramid and food web the can be constructed by the everyday consumers, producers, and decomposers living there, All the way up to the tertiary consumers. (Animals that only eat meat) Third I found a fine example of the impact of human nature. A few weeks before the grass was green and plentiful. Then the [|Head of The Charles] happened. One week after it was bare and where any grass grew at all it was such a pale shade it could not even be called green. Garbage floated through the water and rested on the shore. I feel weird that I am the one to be saying this, as I was there, but it is the truth. And here I feel it is time to end this conclusion, end the end, If you will. If you won’t, then end the conclusion works. But now I’m not lying this time. This really is THE END hello
