Biology - Summary of Interdependance

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…
