The reason that I’m doing this Wiki is because our class went on a field trip to the [|Charles River] and we wrote down all this information so now, we’re going to make a Wiki for the Charles River using all of our gathered information. = == = = = __ Description of Abiotic __ = = My class and I went to the [|Charles River] by foot from our school to there. When we went there, there was going to be a boat race soon, so there were about a dozen porta potties, a bridge, benches, trash-cans and metal and plastic garbage. We also caught plankton with our plankton nets and used magnifying glasses to look for bugs and to get a closer look at plants, and identifying books for bugs and plants to help us identify them. =

__ The Producers, Decomposers, and Consumers __ ** In the Charles River, the producers there were a lot of O ak trees, there was Phytoplankton and there ** **was [|Algae.] In primary consumers, there were Cicadas, Geese, and Dragonflies.** **The Secondary consumers were, Sparrows, Zoo Plankton and little fishes. The tertiary consumers were mice, spiders, and large fish. The decomposers there were Worms, Lichen, and Bacteria. You can see my Charles River ecosystem web here!The Energy Pyramid for every living thing works** **from the bottom to the top. It goes from The Sun, to the decomposers, to** **Producers, then Primary Consumers to Secondary Consumers to Tertiary Consumers a** ** nd last but not least, it all goes back to Decomposers. The way theEnergy Pyramid works is that everything above you eats you. You can also see my energy pyramid here. ** = = = = = = = __ Summary __ = = I discovered many things at the [|Charles River]. The most important thing that I learned was that we need to keep our Oceans, Rivers, and even Ponds clean because they are starting to get contaminated and who knows how many animals could’ve been living there. Even though the [|Charles River] is very dirty, there are still animals living there. Now, because the river is too contaminated, nobody can swim or play in the river. Going to the [|Charles River] would be more fun if it were cleaner, so please try to keep all of our water ways clean. Thank you. =
