目前，单细胞真核生物与它们的多细胞亲戚一起被归为原生生物界。原生动物、藻类和水霉菌被纳入一个分类单元导致了命名问题、学术无家可归和教学减少。已知的原生动物种类约有4万种。原生动物主要以细菌为食，增加矿化，使其他生物更容易获得营养；大多数是水生的，但它们也是广泛存在的动物寄生虫和共生体。综述了它们的生物量、在食物链中的作用、作为共生菌和病原体的作用以及作为生物监测仪的价值。为了更准确地评价原生动物在生态系统中的作用，必须改进目前生态工作中原生动物分类标准较差的现状。随着原生动物学从大学课程中消失，应对该领域现有和新挑战的人力资源正在减少，这一问题需要得到解决。
The unicellular eukaryotes are currently grouped in the kingdom Protista, together with their multicellular relatives. The inclusion of protozoa, algae and water moulds in a single taxon has resulted in nomenclatural problems, academic homelessness, and a reduction in their teaching. There are around 40 000 described protozoan protist species. Protozoa are principally grazers of bacteria, increasing mineralization and making nutrients more available to other organisms; most are aquatic, but they are also widespread animal parasites and symbionts. Their biomass, role in food chains, roles as mutualists and pathogens, and value as biomonitors are reviewed. To assess the role of protozoa in ecosystems more accurately, the current poor taxonomic standards in ecological work on protozoa must be improved. The manpower to respond to existing and new challenges in the field is declining as protozoology disappears from university courses and this problem needs to be addressed.
