B. Food2: Where does it come from?

  1. Autotrophism: Auto means self, and Trophism means to feed. Autotrophism is used mostly in plants, due to Photosynthesis, which produces food for the plants, so they survive.
  2. Photosynthesis: is the process in which plants take 6CO2 + 12H2O and use light to convert it into C6H12O6+6O+6H2O+6O2.  The underlined part of the formula is Glucose, which is food for the plants, and the rest is oxygen.
  3. Light and Color: Light is mainly electromagnetic waves that move in different spectrums.  We see color because the light coming from the sun is called white light, in that light are the colors Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Now what makes a green leaf green is that the leaf absorbs every color except green in fact it reflects it so you see green.
