Learn how chemoautotrophs produce food by oxidizing inorganic substances and using chemosynthesis to survive without sunlight.
Discover how autotrophic nutrition works with photosynthesis, where plants convert sunlight, CO2, and water into glucose and oxygen.
Discover why plants are the most familiar autotrophs and how photosynthesis sustains life by producing oxygen and food.
Discover why photosynthesis is the primary mode of nutrition in plants, fueling growth and oxygen production on Earth.
Discover why a tree is an autotroph and how it uses photosynthesis to create energy from sunlight, water, and carbon dioxide.
Discover why green plants are autotrophic and how they produce food through photosynthesis using sunlight, water, and carbon dioxide.
Learn what autotrophic nutrition is and how organisms produce their own food through photosynthesis and chemosynthesis.
