Sample Written Response Question a) Draw a possible food web involving frogs and at least 6 other organisms. You do not have to use actual illustrations of the plants and animals – you can use words and arrows to complete your food web. Label all trophic levels and type of organism at that level (e.g. producer, primary consumer, etc.) b) Predict what might happen to the food web you constructed above if all of the frogs died and explain how these events could affect the stability of a wetland ecosystem.
