Is a protist an animal? No, animals are grouped in a separate kingdom of their own. Protists are multicellular, they have many cells, so they are not bacteria. Protists are not as complex and have a simpler cellular organization than plants, animals, or fungi, which is one of the reasons why protists have their own separate kingdom. Protists generally live in water examples of which include simpler algaes and other types of microscopic organisms.
Although its classification is a work in progress, chlorella clearly has never been classified as animal, only a plant or protist. How does krill compare to chlorella?
Krill is known for its omega-3 fat content, specifically DHA. Krill has been classified in the animal kingdom because it has a nervous system, digestive system, eyes, and other structures and functions in common with animals.
Krill is a small animal at 5 cm in length. By contrast, chlorella is 0. In summary, spirulina is a type of cyanobacteria classified in the bacteria kingdom, while chlorella is a type of algae that has been historically considered in either the plant kingdom or the protist kingdom. Clearly neither spirulina nor chlorella has ever been grouped in the animal kingdom.

Whittaker has used five criteria for delimiting the different kingdoms, i Complexity of cell structure, prokaryotic and eukaryotic ii Complexity of body structure or structural organization, unicellular and multicellular, iii Mode of nutrition which is divergent in multicellular kingdoms, iv Ecological life style like producers plantae , decomposers fungi and consumers animalia , v Phylogenetic relationship.
When such characteristics were considered, the fungi were placed in a separate kingdom - Kingdom Fungi. All prokaryotic organisms were grouped together under Kingdom Monera and the unicellular eukaryotic organisms were placed in Kingdom Protista. Kingdom Protista has brought together Chlamydomonas, Chlorella earlier placed in Algae within Plants and both having cell walls with Paramoecium and Amoeba which were earlier place in the animal kingdom which lack cell wall.
It has put together organisms which, in earlier classifications, were placed in different kingdoms. This happened because the criteria for classification changed. Which one of the biomolecules is correctly characterised Biomolecules.
