Question: Describe the process of photosynthesis and its significance in the ecosystem.

  1. Answer: Photosynthesis is the biochemical process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose and other organic molecules.

  2. It occurs in chloroplasts, primarily in the leaves of plants. During photosynthesis, carbon dioxide and water are combined in the presence of sunlight and chlorophyll to produce glucose and oxygen.

  3. The overall chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. Photosynthesis is crucial for the ecosystem as it is the primary means by which energy enters the food chain.

  4. It provides oxygen for aerobic respiration in organisms and serves as the foundation of most ecosystems' food webs.
