Question

How does some protozoa form a link of food chain

Answer 1

Answer:

 As components of the micro- and meiofauna, protozoa are an important food source for macroinvertebrates. Thus, the ecological role of protozoa in the transfer of bacterial and algal production to successive trophic levels is important. As predators, they prey upon unicellular or filamentous algae, bacteria, and microfungi. Protozoan species include both herbivores and consumers in the decomposer link of the food chain.
