They have in common that they are single-celled and heterotrophic eukaryotes, have a membrane-bound nucleus, are nonfilamentous, and are confined to moist or aquatic habitats, ubiquitous worldwide. Many are symbionts of other organisms, and some species are parasites.  ]]></termNote><termCreatedDate>2026-03-30 20:21:40</termCreatedDate><relation><relationType>UF</relationType><termId>31303699</termId><termName>Protozoa</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31303700</termId><termName>protozoan</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31303701</termId><termName>protozoons</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31298607</termId><termName>Eukaryota</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31303718</termId><termName>microorganisms</termName><termType>PT</termType></relation></term>  </Zthes>
