Illustrate the energy relationships between plants and animals in an ecosystem with a colorful poster.
As students discuss energy needs of living things, they realize that all organisms in an environment interact with each other either directly or indirectly through a network of food chains known as a food web. Students review the roles of producers, consumers and decomposers and the order of energy flow within an ecosystem. Further exploration of various order consumers and classification as herbivore, carnivore or omnivore demonstrates the diversity of living things. Such knowledge prepares students for analysis of ecosystems and determination of existing food webs in a given area.
Students select images of living things and organize them on a food web poster to effectively demonstrate an understanding of the flow of energy from one organism to another in a given ecosystem or environment.
Note: The Spiderweb #3 has been retired. This project can be created without the Spiderweb to demonstrate the food web concept. If desired, the teacher may hand-cut a 10" Spiderweb.
Supplies Used: Cardstock, Chalk, Double-Sided Tape, Glue, Marking Pen
The teacher will die-cut the materials for student use prior to the lesson.
