This is a sentence of the lesson «Who eats whom: predators, prey, scavengers and decomposers» of the biology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Venus flytrap, plant predator, predator, raindrop), what happens, when and where, as Mova's frames read it from the tree.
