Morphology
Ascophyllum + nodosum
This is a scientific Latin binomial (genus + species) composed of technical or Latin elements rather than ordinary English words; one element ('nodosum') is not a standard dictionary word. Even if a learner knew the genus term, B1 learners will not be able to derive the everyday meaning 'a type of brown seaweed used as fertilizer/animal feed' from these Latin/technical constituents, so the expression is not compositionally transparent.
Etymology
Ascophyllum nodosum gets its name from the parts Ascophyllum meaning 'leaf bag' and nodosum meaning 'knotty'. Its long stems have round bladders that look like little knots, so people call it 'knotted wrack' and often use it as a large brown seaweed for fertilizer.
