Sun energy
In
only 8 minutes the sun supplies the same amount of energy that all mankind
in the world uses up in one year.
The
energy supplier for nature is exclusively the sun. All chlorophyll-
containing organisms (seed plants, ferns, mosses, algaes) accomplish
photosynthesis with the help of the sunlight. This vital metabolic
reaction takes carbon dioxide
(CO2) from air and produces glucose
as well as oxygen. Without the freed oxygen and glucose, a life for
animals and humans on earth would be impossible.
