Protozoans are alive. According to every animal book, an animal is anything that is alive apart from plants. Even humans are animals.
Protozoans are eukaryotic, single-celled organisms with complex cellular structures and can be parasitic or free-living, while bacteria are prokaryotic, single-celled organisms that are much smaller in size compared to protozoans and have simpler cellular structures. Additionally, some bacteria can cause diseases in humans and other organisms, whereas protozoans are generally not known to cause diseases.
No, not all protozoans are prokaryotic and autotrophic. Protozoans are eukaryotic organisms that can be autotrophic or heterotrophic. Autotrophic protozoans can photosynthesize like plants, while heterotrophic protozoans rely on organic matter for nutrition.
