__ INTRODUCTION __

Hi! I am a student in the sixth grade at the [|Amigos School] in Cambridge. The reason I’m doing this WIKI is because I want people to know what goes on in the [|Charles River]. Have you ever known what really lies there? I will tell you everything I know about it from the field trips we took to see it. So stick with the flow and read on! __ ABIOTIC __ Our adventure continued at the [|Charles River]. To get there, we walked only five minutes. The river had a lot of abiotic things, including water, dirt, bridges, concrete, and things like bottles and plastic bags. You could always hear the cars roaming around and the birds chirping to get your attention. Apart from all the water and trees, you could always see people running or biking for some exercise. And guess what? We got the best weather you could ask for. It was sunny and not too hot and not too cold, just right with a few clouds in the sky. To get all the information about the producers, decomposers, producers, etc., we had to use magnifying glasses, some nets to catch plankton, and books to identify bugs and plants. All this helped **a lot** in investigating the [|Charles River.] But most of all, the [|World Water Monitoring Day Kit] did all the work by finding the water information.

__ BIOTIC __ So here I am in the [|Charles River ecosystem]. In this ecosystem, we saw a lot of producers. Some of the producers in the [|Charles River] were algae, grass, and an oak tree. Some of the primary consumers were butterflies, dragonflies, and geese. Some secondary consumers were zooplankton, some sparrows, and a lot of little fishes. Three tertiary consumers we saw were spiders, a large fish, and mice. These all belong in an energy pyramid, with even more organisms. But of course, you can’t forget the decomposers: bacteria, worms, and mold. All the organisms help one another survive. First the sun gives energy to everyone, but especially to the producers so they can produce their own food. The primary consumers eat the producers, so they need them to survive. The secondary consumers need the producers and the primary consumers to survive. And finally, the tertiary consumers need the secondary consumers. In the end, the decomposers break down everything.

During the field trip, I learned how to identify bugs and plants with a book. One of the plants I identified was a purple flower that I learned was called Greek Valerian flower. Something else I learned was how to use a plankton net, to catch plankton. All the water goes through the holes in the net, but somehow the plankton ends in a tube at the bottom. Finally the last thing I did was try to catch a big spider and learned that it is not as easy as it looks. Over all, I learned a ton about producers decomposers, and consumers, but what I really learned was what really lies in the [|Charles River] ecosystem, and I hope you have too!
