Explanation:
Detailed explanation-1: -Chemosynthesis is a term coined by Wilhelm Pfeffer in 1897 to explain how plants and some organisms produce food in the absence of sunlight and oxygen. Instead of these raw materials, chemosynthetic organisms use inorganic compounds to produce glucose, giving them energy.
Detailed explanation-2: -Chemosynthetic bacteria are capable of oxidising various inorganic substances such as nitrates, nitrites and ammonia and use the energy released for their ATP production. So, they are autotrophs and not heterotrophs.
