|
photosynthesis

|
|
protein synthesis

|
DNA synthesis

Explanation:
Detailed explanation-1: -Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.
Detailed explanation-2: -Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.
Detailed explanation-3: -The chemical equation for chemosynthesis is as follows: 18H2S + 6CO2 + 3O2
