FAQs & Answers

  1. What is an autotroph? An autotroph is an organism that can produce its own food using light (photosynthesis) or chemical energy (chemosynthesis), serving as a primary producer in ecosystems.
  2. How do autotrophs contribute to the environment? Autotrophs produce oxygen and form the base of the food chain by creating organic material that supports other organisms in ecosystems.
  3. What is the difference between photosynthetic and chemosynthetic autotrophs? Photosynthetic autotrophs use sunlight to produce food, while chemosynthetic autotrophs obtain energy by oxidizing inorganic substances.
  4. Can you give examples of autotrophic organisms? Examples include green plants, algae, cyanobacteria, and certain bacteria like those found near hydrothermal vents.
