Pond Food Web Directions: READ ALL DIRECTIONS VERY CAREFULLY!!!
 Just as you did for your foodweb earlier in the year, except on a smaller scale (on a piece of computer paper
instead of a poster board)
 The only difference is that instead of coloring in the circles based on niche, you will color in the circles
based on the organisms frequency. This will help you in determining how many there are of each organism
when analyzing your foodweb on the conclusion.
 A key that has colors for each frequency value (#1-5)
