Why are protozoa called early animals?

Expert Answer
Dear Student,
Protozoans are called early animals because they are regarded as ancestors of all multicellular eukaryotic organisms. They belong to the kingdom Protista. Phylogenetically the protista kingdom acts as a connecting link between the prokaryotic kingdom Monera on one hand and the complex multicellular kingdoms of fungi, plants and animals on the other hand.
Bryophytes are called 'amphibians of the plant kingdom' due to their peculiar type of habitats. They are fundamentally terrestrial plants but require presence of water to complete their life cycle.
We hope that clarifies your query.
