Which of the following protozoans feeds parasitically
Answer Details
Protozoans are single-celled organisms that belong to the kingdom Protista. Some protozoans are free-living, while others are parasitic and feed on other organisms.
Out of the options given, the protozoan that feeds parasitically is Plasmodium. Plasmodium is the protozoan that causes malaria, a life-threatening disease that affects millions of people worldwide. Plasmodium feeds parasitically on red blood cells, causing them to rupture and leading to the symptoms of malaria, including fever, chills, and anemia.
Paramecium is a free-living protozoan that feeds on bacteria and other small organisms through a process called phagocytosis. Chlamydomonas and Euglena are also free-living protozoans that are capable of photosynthesis and can produce their food.
Therefore, the answer to this question is Plasmodium, as it is the only protozoan in the list that feeds parasitically.
