Question

Please Help!!!! Mass extinctions have occurred repeatedly during the course of Earth's history. One of these events occurred at the end of the Cretaceous Period, during which the dinosaurs became extinct. Mammals flourished after the dinosaurs were gone. This led to a variety of genetically diverse species. Why did the mammals suddenly start diverging into different species after the dinosaurs were gone? a. Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce. b. Once the dinosaurs were gone, the mammals started having larger numbers of offspring in each litter to fill the empty niches. c. The mammals chose to move into the vacant niches the dinosaurs had occupied and change their body shapes to suit these new environments. d. Mammals began mutating rapidly once the dinosaurs died out and were able to create new species based on the mutations.

Answer 1

Answer:

Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce

Explanation:

Answer 2

Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce.

What is the maximum likely to take place if predators are brought to an environment without acknowledged predators?

With no predators to manipulate the populace and modify feeding behavior, the prey species quickly degrade and over-run their habitat. As food becomes scarce, the population turns unwell and malnourished, and could both flow or crash.

What takes place whilst a keystone species is removed from an ecosystem?

Keystone species have low practical redundancy. which means if the species were to vanish from the environment, no other species might be capable of filling its ecological niche. The atmosphere could be pressured to considerably change, permitting new and possibly invasive species to populate the habitat.
