I told my DD about the example and it gave her a good belly laugh, but initially she was confused about the order, and she thought it was in the wrong direction...(maybe this is just the way she thinks so take it with a grain of salt)

(no cavemen didn't live at the same time as T-rex) - > T-Rex eats smaller dino -> smaller dino eats plant -> plant uses energy from sun to grow

but she's very exact with patterns, sometimes literal (not always, depends upon the subject.)
