Morphology
The sense of a pyramid-shaped diagram relating to food or levels of food (producers up to predators) is directly inferable from combining 'food' (what is eaten/energy source) with 'pyramid' (a triangular/hierarchical shape). This is a compositional, cross-linguistically common naming pattern for diagrams, so a B1 learner who knows the constituents would understand the general meaning even if they lack detailed ecological terminology.
Etymology
The noun food pyramid comes from a simple picture shaped like a pyramid that shows how food moves from many plants and small animals at the wide bottom to few big animals at the narrow top. So the picture shows the 'levels' in an ecosystem and explains why 'top predators' are rarer.
