And, again, its all free. Surface tension of water is basis for transpiration Define transpiration = evaporation of water from leaves, via stomata (specially adapted holes, typically on leaf undersides, designed for gas exchange) Evaporation of water generates negative pressure within leaves, which pulls more water up from ground Up to 50% or more of water that falls can be transpired by plants Plants pull water from ground in transport vessels (xylem tissue, formed from hollow cells, end-to-end) Water moves in these tubes via capillary action This transport of water moves nutrients to leaves, stems, Surface tension of water also influences water availability in different soil types Consider good soil for plants (loam) = mixture of fine clay, intermediate sized silt, coarse sand Soil properties determine curve of soil water potential versus soil water percent (next slide) Water potential measured in atmospheres (= strength of force needed to pull water from soil) Wilting point (15 atmospheres) determined by strong surface tension of water, close to particles Field capacity (ca.

If you feed a goldfish too much, the uneaten food will, supply bacteria with the nutrients and energy they need to, grow exponentially, ultimately using up all the oxygen, Smith and Smith, Ecology and Field Biology, Merely surviving is not the same as surviving AND, Some organisms can survive and reproduce under conditions, where other organisms cannot survive at all, and others can, Some organisms actually require conditions that would kill, The range of tolerances for an organism is not, individuals may acclimate to them and shift their, This, short term, seasonal shift in tolerances is, Ptarmigans are northern birds adapted to the cold, winters they experience in Canada, Alaska, and, During the summer, these birds acclimatize to. compensation point can also do this as a drawdown graph. Boasting an impressive range of designs, they will support your presentations with inspiring background photos or videos that support your themes, set the right mood, enhance your credibility and inspire your audiences.
