Re: [Phys-l] Pres. Obama to eliminate testing portion of NCLB



They are decomposers and actually feed on dead vegitation. This is of
course completely different from green plants which feed on air and water
plus trace amounts of minerals. Mushrooms extract significan nutrition from
the soil, while green plants do not. Green plants derive most of their
material from the air.

Trees DO NOT eat from underground, they manufacture their substance from the
air and water. They only extract a small amount of material from the soil.
It is true that the water comes from the ground, but the idea that the soil
provides the material to make green plants is a huge misconception. By
weight most of the material comes from the carbon dioxide from the air. OK,
plants do contain water.

If you grow a large plant in a pot and weigh the soil before and after you
grow the plant you will notice very little difference. This is assuming you
can get all of the soil off of the roots. Indeed you can grow plants and
end up with a plant whose weight is many times the original weight of the
soil.

Ah well, you find these misconceptions all over the place, especially on
these simple web answers. Does anyone know how to contribute to that Wiki
to correct the misconception?
