What is chemosythetic organism?

Answer 1

A chemosynthetic organism is an organism that manufactures it's own food by a process of chemosynthesis.

Answer 2

Chemosynthetic organisms are able to produce their own food using inorganic compounds instead of sunlight. These organisms typically live in environments with limited sunlight, such as deep-sea hydrothermal vents, where they convert chemicals like hydrogen sulfide into energy through a process similar to photosynthesis. Chemosynthesis forms the basis of unique ecosystems in these extreme environments.
