#autotrophic nutrition
- Autotrophic — Pertaining or relating to autotrophy; specific to the autonomous nutritional mode based on the synthesis of organic substances from inorganic compounds. This structural attribute describes metabolic processes, enzymatic systems, or cellular growth phases where external energy is chemically stored without dependency on other living organisms.
- Autotrophy — The property, quality, or way of life of autotrophic organisms, characterized by the physiological capacity to synthesize their own organic substances required for nutrition and growth from simple inorganic compounds, utilizing an external energy source (light or chemical). This phenomenon represents the energetic foundation of most terrestrial and aquatic ecosystems, ensuring carbon fixation in the biosphere.
