Not much can be said about the biology of an organism until one knows how it provides for itself. Thus, nutritional mode, along with size (Chapter 4) and architecture (Chapter 5) provide the basis for ecological comparisons because they impose broad constraints as well as opportunities. In this chapter I examine how living forms can be grouped depending on which resources they use and how they go about harvesting them. Broadly speaking, the issue is that portion of Figure 1.1 (Chapter 1) concerning resource acquisition.
