Protists are very diverse, and many different classification schemes have been used to define relationships between the protists. traditionally, protists have been classified by their source of energy and nutrients, whereas newer classification schemes use mode of locomotion. how are amoeboids classified using both of these schemes?

By using both of these schemes, energy source and locomotion, amoeboids can be classified properly. Both schemes play an important part of amoeboid’s taxonomy classification because these organisms changes its shape when feeding. Amoebas are traditionally classified under sub-phylum Sarcodina, single-celled with pseudopods (use for locomotion) but recent studies show that they are not monophyletic and actually belong to other groups of organisms — with locomotion and source of nutrients as basis.

Ibelieve the answer is c.
