Food Web Project

The Context: Energy flows in ecosystems in food chains and food webs. A food chain is a series of events in which one organism eats another and obtains energy. A food web consists of many overlapping food chains.

The Challenge: You will be given pictures of plants and animals that are found within the deciduous forest ecosystem. You are to construct your own food web using the pictures given.

Limitations:

·  This is an independent project

·  You will complete this assignment in 1 full class period

Rules:

·  All food webs must contain

o  1 sun

o  1 decomposer

o  14 different organisms

o  25 links

·  All pictures used MUST be neatly and realistically colored and cut out

·  Pictures will be glued onto a large piece of construction paper

·  Glue the sun on the top of your poster to show the original source of energy. THIS SHOULD NOT BE LINKED TO ANY ORGANISMS!

·  Use books provided to help determine the relationship between different organisms

·  Do not glue ANYTHING down until you have laid out the web first

·  Make sure all pictures are placed in a meaningful manner

·  Draw arrows to indicate the flow of energy and the relationship between organisms. MAKE SURE THEY ARE POINTING THE CORRECT DIRECTION! USE A RULER!!

·  Number your arrows with a small number to keep track of how many arrows you have created.
