Morphology
pond-scum + parasite
The phrase is directly compositional: 'pond-scum' (the algal/organic film on a pond) + 'parasite' (an organism that feeds on a host) yields an organism that parasitizes pond scum. This straightforward noun+noun relation follows common cross-linguistic patterns, so a B1 learner who knows the constituents would readily infer the meaning.
Etymology
Pond-scum parasite comes from a simple image: a tiny fungus living on the green slime that grows in ponds. The part pond-scum points to the slime and parasite shows it feeds on that slime, so the name means 'a parasite that lives on pond scum'.
