The Norway Spruce receives its food via photosynthesis, meaning its primary source of food is glucose.  Glucose is broken down by cellular respiration and makes ATP, which is energy in its usable form.  This particular tree has to overcome cold conditions during the winter and low water availability during droughts.  Like other vascular plants, glucose is transported via its phloem near wherever it was produced, and then travels elsewhere by diffusion and osmotic pressure to where it is needed or will be stored.  Transportation of water is possible via the xylem, which utilizes four properties that allow the transportation of water to happen.  These are transpiration, adhesion, cohesion, and tension.  In order to prevent a build up of pressure within the xylem, water is stored in mesophyll cells.  The Norway Spruce also requires other inorganic nutrients, which are retrieved by its root system, and then transported via the xylem.
