Morphology
yellow-green + algae
The phrase is directly compositional: the adjective 'yellow-green' modifies 'algae', so a B1 learner who knows both words will understand it as algae that are yellow-green in color. The dictionary's taxonomic and pigment-detail is specialist information but does not prevent basic, cross-linguistically common adjective+noun interpretation.
Etymology
Yellow-green algae names tiny water plants. These algae have a yellow pigment that hides some of their green, so they look 'yellow-green', and that's why the name refers to these yellowish water plants.
