REVISION SUMMARY FOR BIOLOGY - INTERDEPENDANCE

  • Life depends on solar energy absorbed during photosynthesis and stored in chemicals like starch.
  • Autotrophs make food from minerals, carbon dioxide, and water but heterotrophs need ready - made food.
  • Chlorophyll absorbs light for photosynthesis. The equation is:

Carbon Dioxide + Water -> Glucose + Oxygen

  • Some glucose is used for respiration and to make cellulose, protein, starch and chlorophyll.
  • Nitrates are absorbed and added to glucose to make proteins.
  • They are absorbed by active transport…
