Yes, protozoans are invertebrates because they do not possess a backbone or spinal column. They are single-celled organisms that belong to the kingdom Protista.

They are all eukaryotes, and live in moist surroundings.Most protozoans are unicellular, but not all.
Microscopic protozoans that are found in the gut of insects are commonly referred to as insect gut protozoa. These protozoa live symbiotically with insects and can play important roles in the digestion and nutrition of their hosts. They are diverse in their morphology, behavior, and ecological functions within the insect gut ecosystem.
Protozoans are preyed upon by a variety of organisms, including other protozoans, microscopic animals like nematodes and rotifers, and larger organisms like fish and amphibians. Additionally, some protozoans are susceptible to parasites and pathogens that feed on them.
Protozoans are single-celled organisms that belong to the protist kingdom. They are mostly microscopic and exhibit a wide range of shapes and structures. Protozoans are known for their ability to move using cilia, flagella, or pseudopods, and they obtain nutrients through various modes such as phagocytosis or diffusion.
Protists can be both microscopic and macroscopic, depending on the species. Many protists are single-celled organisms that are too small to be seen without a microscope, while others, such as seaweed, can be large and visible to the naked eye.
Protozoans are single-celled organisms that belong to the Protista kingdom. They are found in various aquatic and terrestrial environments, and they can be free-living or parasitic. Protozoans play important roles in nutrient cycling and food webs.
Amoebas are preyed upon by various organisms such as other protists, small invertebrates, and even some fungi. Predators use various methods including engulfing, engulfing and dissolving, or puncturing the cell membrane to consume amoebas.
Protozoans and rotifers are both microscopic organisms found in water environments, but they belong to different taxonomic groups. Protozoans are single-celled organisms belonging to the Protista kingdom, while rotifers are multicellular organisms belonging to the Animalia kingdom. The mistaken identity may occur due to their similar size and movements in water.
Invertebrates do not have backbones and the list is long. A few examples include the insects, worms, mollusks, echinoderms, arachnids, gastropods, protozoans, etc.
