A class observed grasshoppers, frogs, mice, snakes, and owls in a grassy field.  They are all part of the same food web. 

Students combined their observation of what the organisms eat in the table.

On paper, draw a food web with all of the organisms listed in the table above. 

When drawing the food web, be sure to use the names of all the organisms and draw arrows to trace the energy flow among the organisms.  

Once your food web is complete, you will upload an image of it.
