Morphology

heterotroph = hetero + troph

Built from the combining forms 'hetero-' (other) + '-troph' (feeding/nourishment); the overall composition is meaningful in biological contexts, but '-troph' is a technical combining form not familiar to all learners.

Etymology

Heterotroph comes from Greek parts hetero- meaning 'other' and -troph meaning 'food' or 'feeding'. So a heterotroph is a living thing that must get its food from other organisms, not make it itself like an autotroph.
