Protists: Characteristics and Examples

Protists are a diverse group of mostly single-celled organisms that don't fit into other life categories. They include animal-like, plant-like, and fungus-like types. Animal-like protists, or protozoa, consume food like animals. Plant-like protists, or algae, produce food from sunlight. Fungus-like protists decompose organic material. Protists inhabit various environments, from oceans to soil, showcasing their unique diversity.
