All living organisms can be broadly divided into two groups — prokaryotes and eukaryotes — which are distinguished by the relative complexity of their cells. Monerans are present in both aerobic and anaerobic environment. These are usually aquatic, present in the soil or in areas with moisture. According to the categories, they have different modes of nutrition, like heterotrophy or autotropohy. What is Kingdom Protista and its Characteristics | Class 11 Biology.
