The acorn woodpecker is the only bird that can eat chestnuts and acorns. These birds hide the seeds in the cracks of tree bark. Squirrels will raid the bird's hiding spots and in turn hide the seeds on the ground. Most of the seeds are eventually eaten but a few grow into large chestnut and oak trees.
Green miracle
Green miracle Breathing is something we all do unconsciously.
Without oxygen, we would die. Plants producing this life-sustaining
gas churn it out as a by-product of photosynthesis, but exactly how
they do it is a little puzzling. Chemists at Yale University have
now created an artificial version of a plant's oxygen machine as a
way to learn more about how plants split water molecules and
generate oxygen. The researchers hope that understanding this
technique will eventually lead to new ways of harvesting the power
of the sun and producing oxygen and hydrogen, the gas which may be
the fuel of the future. 14 AUGUST 1999, P. 26-27
