Chemosynthesis

Chemosynthesis is a biological process through which certain organisms, primarily bacteria, create their own food using chemical energy rather than sunlight. These organisms typically live in extreme environments, such as deep-sea hydrothermal vents, where they utilize chemicals like hydrogen sulfide to produce glucose and other organic compounds. This process is vital for life in these ecosystems, as it serves as the base of the food chain, supporting a diverse range of organisms that rely on chemosynthetic bacteria for nourishment, analogous to how plants rely on photosynthesis.
