Fourth graders continue to dig deeper into their understanding of how an ecosystem functions. After learning about the types of organisms in an ecosystem, each fourth grader was transformed into a producer, consumer, or decomposer in a river ecosystem. Two students were also magically transformed into the river and the sun, two non-living factors that affect an ecosystem, too.
Meeting and greeting one another, they learned the possible organisms they may depend up for food or to stay away from! We created a model of a river ecosystem food web to see how everything from the sun to the river is actually connected. Check out our food web design to the left! We used string to represent the relationships between organisms. It was "very complicated!" said a student! Yes, food webs are quite complicated indeed!
