The bacteria which oxidize various inorganic substances anduse the released energy for the synthesis of food are called
1 Archaebacteria
2 Heterotrophic bacteria
3 Photosynthetic autotrophic bacteria
4 Chemosynthetic autotrophic bacteria
Explanation:
(d) Chemosynthetic autotrophic bacteria use the energy obtained by the oxidation of chemicals for the synthesis of food. They play a great role in recycling of nutrients like nitrogen, phosphorous, iron and sulphur.
