The asteroid: the day the dinosaurs died and who survived, sentence 2

Without sunlight the plants could not make food, so they died, then the plant-eaters starved, then the meat-eaters: the food chain fell down from the bottom like a tower of blocks.

Who acts: plants, plant eaters, food chain · What happens: not make, die, starve, fall down · To what, where: food, bottom

This is a sentence of the lesson «The asteroid: the day the dinosaurs died and who survived» 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 (plants, plant eaters, food chain), what happens, when and where, as Mova's frames read it from the tree.
