Plants take water from the ground
through their roots, and carbon
dioxide from the air and using sunshine, it makes, oxygen and a
glucose. Oxygen is in the air that we need to breathe. Trees
use glucose as food for energy and as a building block for growing.
As summer ends and autumn comes, the
days get shorter and shorter. This is how the trees "know" to begin
getting ready for winter.
During winter, there is not enough
light or water for photosynthesis. The trees will rest, and live off the food
they stored during the summer. As the bright green fades away, we begin to see
yellow and orange colors. Small amounts of these colors have been in the leaves
all along. We just can't see them in the summer, because they are covered up by
the green chlorophyll. (That’s the
story of photosynthesis in 150 words or less) .
Meanwhile back at my office: Sometimes all grace and diplomacy escapes
me when I get phone calls like this:
“You have to do something quick all
the trees are dying….”
“Can you tell me what is happening?”
“The leaves are turning yellow and
gold and brown and then they fall on the ground….”
“Uhhhhh, that’s why they call it fall.”
