The Representation of Mosquitoes - Assignment Example Consequently, a select species of mosquitoes survive the effects of the pesticide. Certain mosquitoes are likely to survive the effects of pesticide due to a selective advantage. This selective advantage results in a greater resistance to the genes of certain mosquitoes. As a result, they are able to survive the effects of a pesticide spray as other mosquitoes die. The mosquitoes that are able to survive the effects of the pesticide possess a genetic resistance to the pesticide. As the mosquitoes achieve maturity, they reproduce and transfer the genetic resistance to the subsequent generation. In the process, the new generation acquires an increase in the number of alleles that develop further resistance to the pesticide within the population. A systematic and continuous application of the selective pressure against the pesticide results in a mutual resistance against the pesticide within the mosquito population. Examples of organisms that became extinct before the adaptive radiation are the prehistoric non- avian dinosaurs that were replaced by mammals during the end period of Cretacious. Adaptive radiation refers to a fast evolutionary radiation fuelled by natural selection that is synonymous with an addition of the ecological and morphological diversity of one rapidly changing lineage. It occurs right after extinction since the phenotypes of a new species adapt in conformance to the environment. Consequently, new traits that are beneficial are increasingly evident. The sun acts as a source of energy that is transferred to the producers such as plants. However, the energy is lost through heat. As a result, 10% of the energy from the producers is transferred to primary consumers such as deer, zebras, and other herbivores. As energy is transferred across the trophic levels through consumption, there is a consistent loss of approximately 10%.
