Answer:
One reason that Organism A and Organism C will be placed in different groups will be due to their MODE OF NUTRITION.
As described in the question, Organism A has an autotrophic mode of nutrition which means that it has the capability to produce its own food. Organism C is a heterotroph which means it cannot produce its own food and hence will have different properties as compared to the organism A.
Lactic fermentation occurs in many organisms, but only during a specific process known as anaerobic respiration. Muscles usually receive energy through a process known as cellular respiration[15], but when there is a lack of oxygen in the organism, muscles go through anaerobic respiration.

The answer is the atoms of the reactants have combined to form a new substance. Every product of a chemical equation has to be a new substance. If their is no new substance then, a chemical change never occurred and there is no chemical equation. The new substance never has the same properties as the reactants. That's why they call it a "new" substance. Also, the atoms are the ones that combine. They are not mixed
