Unformatted text preview: transpiration - loss of water from plants, acts to cool plants (releases latent energy) respiration uses stored energy (carbs) to create CO2, H2O, heat net primary production (NPP) - difference between photosynthesis minus respiration measure is biomass (dry weight of organic material) 2. Hydrologic Cycle - most abundant single substance in biosphere is water medium of life processes source of their hydrogen - watery solutions dissolve nutrients residence - bound into plant and animal tissues transit - transpiration-respiration stream 3. Carbon Cycle - one of most basic elements of life continuous states of creation, transformation, decomposition transfer of carbon from CO2 to living matter then back to CO2 = main component...
