Document Summary
Review: organisms with seemingly similar environmental conditions co-exist through resource partitioning: the sun: source of all energy in the planet. It takes 8 minutes and two seconds for light to come from the surface of the dun to the earth. The energy value from the sun 8. 21 j/cm^3/minute or 340 watts. 25% of the energy is absorbed by the atmosphere. 5% is reflected by the surface of the earth. 45% energy fuels the earth: energy is not dissipated to the earth equally. The earth is tilted 23. 5 degrees from the perpendicular. The side tilted towards the sun will have summer. Periapsis: earth is closest to the sun. Apoapsis: earth is furthest away from the sun. More light energy is focused at the equator than the poles. At the poles the light is more spread out: solar angle of incidence. The equator receives more solar energy than the poles.
