Discover how bacteria use chemosynthesis at deep-sea hydrothermal vents to create organic molecules without sunlight, supporting unique ecosystems.
Discover how certain bacteria function as chemoautotrophs by oxidizing inorganic substances to produce organic compounds from carbon dioxide.
Learn how chemoautotrophs produce food by oxidizing inorganic substances and using chemosynthesis to survive without sunlight.
Discover the 3 main types of autotrophs—photoautotrophs, chemoautotrophs, and mixotrophs—and their roles in nature.
Discover 5 examples of autotrophs, organisms that produce their own food through photosynthesis or chemosynthesis.
Discover why photosynthesis is the primary mode of nutrition in plants, fueling growth and oxygen production on Earth.
Discover how Nitrosomonas demonstrates chemoautotrophic nutrition by oxidizing ammonia and contributing to the nitrogen cycle.
Discover two key chemoautotrophs—Nitrosomonas and Sulfolobus—and how they impact nitrogen and sulfur cycles in different environments.
Discover three key organisms that use chemosynthesis: hydrothermal vent bacteria, methanogens, and sulfur-oxidizing bacteria. Learn how they produce energy.
