What to Focus On

  • Biosphere is the organic realm of the earth.
  • It lies at the contact zone of lithosphere, atmosphere and hydrosphere.
  • Life is concentrated in land, coastal and surface-water zones.
  • Ecology studies interactions between organisms and environment.
  • Ecosystem means the system of interactions in a given area.
  • Eco comes from a Greek word meaning household.
  • An ecosystem has energy, biotic and abiotic components.
  • Solar radiation is the main source of energy on earth.
  • Autotrophs are producers; they include phototrophs and chemotrophs.

Common Mistakes to Avoid
