When sun shines on green leaves (chlorophyll), water
combines with carbon dioxide to form sugar and give off oxygen.
When sugar is oxidised in cells, energy is liberated and
carbon dioxide and water are given off as waste products.
The first process is photosynthesis (light together puts)
the second is respiration. They feed off each other. The detailed biochemistry
is common to nearly all living things. This suggests its ancient origins.
They happen in my garden in terms of apples, pears and
plums; but I go one hundred yards to the Coop shop to harvest broccoli, lettuce,
leeks and lots else.
If I am to keep living I have to breathe, pee, poop and eat
plants and animals.
Tough on them.
But thanks.
