This is a sentence of the lesson «What a habitat is: home, food, shelter and fitting in» 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 (frog, tadpoles, adult frogs, losing), what happens, when and where, as Mova's frames read it from the tree.
