How and why do organisms di er in size ? (func8onal diversity 3) Trade o : some trait has bene ts in one context but a cost in another context. Principle of alloca8on: all life func8ons can"t be simultaneously maximized. 1. 2. 1 func8onal diversity 1 : resource acquisi8on. Photo autotrophs: use light energy as the energy source. Photosynthesis: 6co2 + 6h2o -----> c6h12o6 + 6o2. Respira8on: c6h12o6 + 6o2 ------> 6co2 + 6h2o. Note: primary produc8on is a func8on of not just light and carbon dioxide but also of nutrients and trace minerals. Concept one: how to iden8fy whether a element/substance is essen8al for a plant. Process of photosynthesis : chlorophyll a pigment is the primary light harves8ng pigment of green plants.
