Bio: Ch. 34 Nutrition and Digestion 16:39 Passive smoking= breathing second hand smoke -estimated to cause 3,000 deaths from lung disease and 37,000 deaths from heart  disease in non-smokers in the US each year. Ch. 34 Nutrition and Digestion A nutritionally adequate animal diet satisfies three needs: 1. Fuel= chemical energy: calories 2. Organic raw material for biosynthesis (especially carbon-based molecules) 3. Essential nutrients (substances that the animal needs, but cannot synthesize from  any precursors on its own). A nutritionally inadequate animal diet fails to satisfy the three basic needs. 1. Undernourishment-insufficient calories (energy) 2. Over-nourishment- too many calories and too much stored fat 3. Malnourishment- a diet missing one or more essential nutrients.  Energy in nutrients is measured in Calories (kcal= energy to raise the temperature of 1 L of water 1° C).
