Examples of autotrophic bacteria include _Cyanobacteria_, which perform photosynthesis, and _Nitrosomonas_, which derive energy from the oxidation of ammonia. Autotrophic bacteria are crucial for ecosystems as they produce their own food, sustaining other organisms in the food web.

FAQs & Answers

  1. What are autotrophic bacteria? Autotrophic bacteria are microorganisms that produce their own food through processes like photosynthesis or chemosynthesis, using inorganic substances as energy sources.
  2. Can you give examples of autotrophic bacteria? Yes, examples include Cyanobacteria, which perform photosynthesis, and Nitrosomonas, which oxidize ammonia to derive energy.
  3. Why are autotrophic bacteria important in ecosystems? They form the base of many food webs by producing organic compounds from inorganic substances, supporting other organisms and contributing to nutrient cycles.
  4. How do Nitrosomonas bacteria obtain energy? Nitrosomonas bacteria obtain energy by oxidizing ammonia, a process essential in the nitrogen cycle.
