Answer: The extinction of dinosaurs will lead to increase in the prey which they used to consume before extinction.
Explanation:
Many years ago the dinosaurs used to dominate on earth as large mammals. They were plant eater herbivores and animal consumer carnivores. After the extinction of dinosaurs the ecological balance got disturbed. Flowering plants dominated the earth. The large and massive non-bird dinosaurs died but the bird like dinosaurs survived and they passed their traits to some lineages of modern birds.
Darwin reasoned that natural selection organisms had adapted to new environments, giving rise to new species. It is a principle of speciation.
<h3>Speciation, natural selection and environment</h3>
Different environmental pressures (e.g. the type of food) lead to different evolutionary pathways in genetically related organisms.
The organisms subject to different environments evolve as a consequence of natural selection in order to adapt (adjust) to their corresponding environments.
In consequence, this process may eventually lead to speciation due to the emergence of reproductive isolation barriers.
