• B. Q could be a prokaryotic organism that helps in breakdown of dead bodies of plants and animals.
• C. Organism R could be used to obtain antibiotics.
• D. S could be an organism that causes sleeping sickness in humans.

Answer 1

The correct option is B Q could be a prokaryotic organism that helps in breakdown of dead bodies of plants and animals.

• P is a prokaryotic organism Giardia which is a parasitic prokaryote. It causes alimentary diseases once it attaches to the wall of the gut it interferes with the absorption of lipids and fat in the small intestine. The secretions of this organism also cause vomit, loose motions, enteritis, fever, etc.
• Q is a eukaryote Chromalevolata which is formed by an endosymbiotic relationship between red algae and a bikont (a prokaryotic organism with 2 flagella) It simply prepares it food by the process of photosynthesis like other algae the bikont here provides the algal cell with locomotion to collect material for the production of food.
• R is and a fungus called Penicillium notatum which secretes a substance call penicillin which is used as an antibiotic help for killing bacteria and therefore used in the treatment of bacterial infection.
• S is a prokaryotic organism called Trypanosoma it causes sleeping sickness or Chagas disease in vertebrates which are transmitted by its vector tsetse fly when it bites the human.
• Therefore the option B is the correct answer.
