Convert the semantic net shown in Figure 2-5 to a series of facts in a deffacts statement. Use several deftemplates to describe the facts. For example, the IS-A links and AKO links should be relation names and each should have its own deftemplate. Convert the binary decision tree representing animal classification information of Figure 3-3 to a series of facts in a deffacts statement. Show how the links between the nodes can be represented.

Translate the following heuristics below to rules that determine nutrient deficiency. Assume that the plant is normally green. A plant with stunted growth may have a nitrogen deficiency.
