<h2>Asteroid impact and Dinosaur extinction. </h2>

Explanation:

The scientists suggest that when a sufficiently large asteroid or comet struck the earth surface, they might have caused dust particles to rise up in the atmosphere and form a thick covering on the earth blocking the sun rays.

The blocking of sun rays must have resulted in severe colds and plants failed to carry out photosynthesis. Since, the plant died out , the herbivores got extinct because of the lack of food.

The loss of herbivores resulted in shortage of food for carnivores, and the larger carnivores started feeding on the younger population of their own species. Day by day the population size diminished and the dinosaurs along with some other species of plants and animals got extinct.
