Answer:
Charles Darwin
Explanation:
<em>Charles Darwin, a nineteenth-century biologist, studied the notion of natural selection. Natural selection shows how hereditary features of a species can change and evolve. This may result in speciation, the development of a separate new species.</em>
The answer is: <span>D. The population of bluebirds will decrease, leading to an eventual decrease in the number of predators.
The unwanted </span><span>dumping of chemicals causes a decrease in the number of insects. The insects are eaten by bluebirds, but if there is not enough food for the bluebirds, they will die- decrease of birds. If there are less bluebirds, their predators will have less food, so many of them will also die.</span>
The right answer is Damselfish
The damselfish is a species of herbivorous fish that contributes to a balance of marine plants by eating algae among corals, to prevent the proliferation of algae and to promote the growth of coral reefs. The parrotfish (Scaridae) or "coral cleaner" has the same similarity of the diet with the same equilibrium that the damselfish offers, but it can also feed on coral.
