The microbes thriving in acidic environments are termed as acidophiles, and these range from eukaryotes to bacteria and archaea, which are mainly found in diverse acidic surroundings like sulfuric geysers and pools, in the human stomach, and in the regions that get polluted by acid mine drainage.
The mentioned case is not entirely correct as the protons found in the acidic surroundings are not utilized for the generation of ATP as they are not originating from within the cell. In order to sustain their internal acidic pH, the acidophiles exhibit adaptations like the presence of the negatively charged proteins on the surfaces of their membranes so that they can prevent deterioration due to acidic surroundings.

Plants utilizes the sunlight during photosynthesis and are able to prepare there own food.The organisms those who obtained the energy and utilized it from sun are the producers. The food web has various other parts like, The sun which gives the sunlight are being utilized by the plants for production of the food, next are the producers, after that comes the consumers who takes the energy from the producers and in the final their comes the decomposers.
