  1. What is an autotrophic organism? An autotrophic organism is one that can produce its own food from inorganic substances using light or chemical energy, such as plants, algae, and certain bacteria.
  2. How do green plants produce their own food? Green plants produce their own food through photosynthesis by converting sunlight, carbon dioxide, and water into glucose and oxygen.
  3. What role do cyanobacteria play in autotrophy? Cyanobacteria are autotrophic bacteria that perform photosynthesis, producing oxygen and organic compounds that support many ecosystems.
  4. Are algae considered autotrophs? Yes, algae are autotrophic organisms that use sunlight to synthesize their own food through photosynthesis.
