The Kingdom Protista and Protozoans
The Kingdom Protista is full of all sorts of diversity due to anything that isn't an animal, plant, or fungi is put in this Kingdom. There are 4 groups of Protista, single celled animal protists, single celled plant-like protists, multicellular plant-like protists, and fungus-like protists. In these groups there is also sub groups, but they all have characteristics in common to unify them as one kingdom. These characteristics are they are mostly unicellular (some multicellular, all are eukaryotic, most live in water, and can be autotrophic or heterotrophic.
The prefix "pro" means first and "zoa" means animals so it is no surprise that the first group of organisms that contained animal- like characteristics, like being heterotrophic and turning food into energy, are called Protozoans. Although they are animal-like, they are unicellular and reproduce asexually, mainly through binary fission. They are mainly aerobic eukaryotes, and live in many various habitats. The subgroups of Protozoans are Sarcodines (amoebea-like), Mastigotes ( have flagella), Sarcomastigotes, and Ciliates (have cilia).
