Why plants? – Why include plants in a course on dinosaurs? They don't move, lack large teeth and sharp claws, and are non-sentient. The average student (who can spell Deinonychus correctly) hasn't a clue to the genera of even the most common plants. However, without plants, dinosaurs (or any other heterotroph) would not exist. Plants are the basis for global life, trapping the sun's energy in a form useful to consumers. Thus, the photosynthetic efficiency, palatability, and digestibility of plants define the total energy in the system available for use by consumers – and therefore the total biomass of consumers. Additionally, the morphology of individual plants determines the “packages” of food available to herbivores, and in the aggregate, the three-dimensional environment in which the herbivores and their carnivores live.
