5 | | The ''Diet composition'' form is accessed through the ''Navigator window''. Enter diet composition, for all consumers, column by column (i.e., predators are represented by column and their prey by row). The diet compositions of each group should sum to 1. For guidance, the current sum of the fractions representing the food composition is summed at the second-last row (Sum). The last row (1 – Sum) shows the proportion of prey still to be entered. You can use the ''Sum to one'' button at the top of the ''Diet composition'' screen to raise a diet to unity. If diets do not sum to unity when you start basic estimation (i.e., try to balance the model) you will be given the option of having the software do the raising for you, or to return to the diet to do it yourself. |
