Answer:

A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs. Food chain imbalances lead to the starvation of the dinosaurs.

After the dinosaurs went extinct a bunch of new roles were open that used to be inhabited by dinosaurs. The extinction allowed for other animals to grow and evolve in ways they couldn’t when the dinosaurs existed. More specifically the extinction of the dinosaurs led to the rise of mammals in the Cenozoic.
