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

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.

• 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.
