Note:

Group refers to major groups of protists (phyla), for example, Actinopods, sporozoa, ciliates, cryptomonads etc.

Subgroup refers to the major subdivisions of these phyla, for example peridinoid dinoflagellate; heterotrich ciliate, gregarine sporozoan.

Organism refers to genus, for example Amphidinium, Paramecium etc.

Habitat - be specific where you can: Marine planktonic, freshwater benthic

Where several alternative terms are given as alternatives within parentheses, circle or underline the correct answer. Positions are sometimes indicated by reference to the clock face (2:00) etc.
