Hello there!!
I love protozoa so this should be fun.
1. Protozoans are unicellular beings that live in wet environments.
2. Protozoans have 2 prevalent ways of feeding:
a) the most common is utilized by heterotrophs like amoeba. An amoeba extends its elastic body until it completely surrounds the victim. Then the amoeba simply has to digest its food.
b) The second most common is through cilia. Paramecia use this method. The hair-like cilia in its mouth catch hold of food and push the meal into the paramecium's digestive tract.
3) The only protozoan to have its own family is Euglena.
4) Euglena has its own family because it has chloroplasts (meaning it can undergo photosynthesis) but it can also feed like a heterotroph. Because Euglena exhibits both plant and protozoan qualities, it has its own category.
5) Rotifers move by two spinning wheels of cilia. This type of propulsion makes the rotifer a speedy little protozoan.
I hope this answers your question. :)
