TO BE CONSIDERED AS FOOD- WHAT MUST A SUBSTANCE BE MADE OF/CONTAIN? CARBS, FATS, PROTEINS— THINGS WITH CHEMICAL ENERGY— C-C OR C-H BONDS

 Water  Not considered food, but it is essential to all organisms.  Solvent - things can be dissolved in it.  Medium for transporting nutrients and waste  Medium for temperature regulation and chemical processes.

 Vitamins and minerals are  Not considered food but are also important to organisms.  Optimize cellular processes (chemical reactions) helps the organism’s cells run efficiently.

 Which components of soil do you think plants need?  Why do you think they need it?

 Organic matter: decaying remains of plants and animals.  This is found in the top part of the soil and plants don’t have a way to absorb carbs, fats, or proteins from the soil

 Mineral matter: elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, manganese, copper, zinc, boron, chlorine.
