Autotrofitët

Autotrofitët, commonly known as producers, are organisms that create their own food through the process of photosynthesis or chemosynthesis. They are the foundation of most ecosystems, providing the energy and organic matter that sustains other life forms. Photosynthetic autotrophs, such as plants, algae, and cyanobacteria, utilize sunlight, water, and carbon dioxide to produce glucose, a sugar molecule that serves as their energy source. This process releases oxygen as a byproduct, which is essential for the respiration of many organisms. Chemosynthetic autotrophs, found in environments like deep-sea hydrothermal vents, derive energy from chemical reactions involving inorganic compounds such as hydrogen sulfide or ammonia. These organisms play a crucial role in nutrient cycling and forming the base of food webs in environments where sunlight is unavailable. Without autotrophs, the vast majority of life on Earth would not be possible, as they convert inorganic substances into organic compounds that can be consumed by heterotrophs, or consumers.
