Solution
The correct option is B A and C
Bacteria show a wide range of metabolic diversity. For example, in terms of nutritions, they could be autotrophic, chemotrophic and heterotrophic. Hence, we see a wide range of metabolic activities.
When there is a good supply of food and suitable abiotic factors, there is a luxuriant growth of the cyanobacteria which often leads to the formation of blooms in the
water.
Mycoplasmas are organisms that completely lack a cell wall. They are the smallest living cells known and can survive without oxygen. Many mycoplasmas are pathogenic for animals and plants.
