The graph shows the relationship between food intake and calorific or heat equiva- 

 lence of several invertebrates. This information was obtained from published 

 material and synthesized to determine the mathematical relationship which then can 

 be used in a numerical, computerized model to predict the amount of heat that is 

 produced by a given amount of food.
