=**//__The Charles River Ecosystem__//**=

== **//My name is mariapaola2 and I am in the 6th grade at the [|Amigos School]. I am doing this WIKI for my science class. l will write in my WIKI about ecosystems. The trip that I will talk about was to learn about ecosystems. My class went to [|Charles River] in Cambridge Massachusetts to study ecosystems. The Charles River is a very good place to study this because it has a large ecosystem.//** ==

== **The class walked to the Charles River. The day the class wen****t to the Charles River the weather was cold and it was windy. On the land they saw rocks and cars and in the water they saw boats and ducks. My classmates told me they had to use winter jackets because it was cold. My classmates told me they used cups, thermometers and cameras to gather and document the information about ecosystems.** ==

== **The Charles River has a large ecosystem. Ecosystems have producers, consumers, decomposers and abiotic systems. Producers are systems that can make their own food with the sun. The Charles River has producers like moss, trees and flowers. Consumers are systems that need to eat other living systems for energy. The Charles River has consumers like ducks, fish and field mice. Decomposers need to eat dead producers and consumers for energy. There are decomposers like rocket fungi, worms, slugs and centipedes. The energy pyramid is a drawing that explains how all the animals in an ecosystem survive. In the Charles River the consumers need the producers; for example ducks eat the moss. The decomposers need dead consumers and dead producers; for example worms eat dead ducks and moss.** ==

== ** My class walked to the Charles River to learn about ecosystems. I have been learning about ecosystems in my science class. I learned that ecosystems have different types of organisms. I have learned that those organisms are named in the energy pyramid as consumers, producers and decomposers. I learned about abiotic systems. Abiotic systems are non-living things that are around the ecosystem. Some examples of abiotic systems are cars, rocks and boats. I think this trip was very good because everyone learned about ecosystems.** ==
