Energy Flows From the Sun
and Through Lives

The Biosphere is Powered
by a Shower of Solar Energy

 
Our star Sol,
showing huge sunspots
  the solar shower that lifts our spirits

Earth receives two crucial kinds of solar radiation:

Light drives photosynthesis, the foundation of food energy.
Light arrives in quantum packets called photons
Plants, algae, and archaea and cyanobacteria transform sun-energy into packaged food.
Plant-packaged sun energy transfers from life to life
     
Solar Heat drives the water cycle, the winds, the ocean currents
Heat arrives as infra-red waves
 
Earth is at just the right distance from Sol to receive the amount of heat that earthlife needs.

The Energy Pages explore the work of life on earth, which includes:

• the transfer of energy from life to life

• the transformation of energy from form to form
