Part 4: Model Evaluation In science, models are used to represent explanations and predictions. The food chain, food web, and energy pyramid are all models that show feeding relationships and allow us to make predictions. Compare and contrast the strengths and weaknesses of each model by filling in the table below. Model Food Chain 1. Food Web 2. 1. Energy Pyramid 2. 1. 2. List two things this model is useful for illustrating or predicting Identify one feature that this model lacks or one that could lead to a misconception lame
