Answer 2

Answer:

The answer is (d) I, II, and III are true.

Explanation:

Bacteria demonstrate both autotrophic and heterotrophic nutrition. Autotrophic nutrition concerns the manufacturing of organic materials from inorganic raw materials with the use of energy obtained from outside. It is of two classes, chemosynthesis, and photosynthesis. The bacteria performing these modes of nutrition exist respectively named chemoautotrophs. The vast majority of bacteria exist as heterotrophs. The vast majority of bacteria exist as heterotrophs, i.e., they do different organisms or on dead organic matter for food.  

Heterotrophic nutrition exists as the mode of nutrition where the organism is unable to prepare its food and therefore, depends upon plants or other organisms for nutrition.

Hence,

The correct option (d) I, II, and III are true.
