3. Composition 71% hydrogen 27.1% helium less than 2% of all other elements – Oxygen, Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron and Sulfur – The mass of the sun is over 99.8% of the mass of the entire known solar system http://hyperphysics.phy-astr.gsu.edu/hbase/solar/sun.html#c1

4. Distance From the sun to the Earth is 149,000,000 km. This equals 1 AU (Astronomical Unit). http://hyperphysics.phy-astr.gsu.edu/hbase/solar/sun.html#c1

5. Energy Almost all life on earth is maintained by energy from the sun. Plants synthesize sugar molecules from carbon dioxide and water. This energy can then be transferred to other organisms and utilized throughout a food web. http://www.project2061.org/publications/sfaa/online/chap5.his insufficient, tm

6. The amount of life possible that any environment can sustain is limited to the basic resources of energy, minerals, and water. When the inflow of resources desertification and depletion of minerals occurs. http://www.project2061.org/publications/sfaa/online/chap5.his insufficient, tm
