Answer: D.adding more shelter for frogs
Food chain can be defined as the linear series of food and energy distribution, in which one organism is consumed by the other in order to obtain nutrient and energy.
In the given situation a person wants to reduce the mosquito population, which is present as a primary and secondary consume in the pond food chain. By adding more shelters for frogs can reduce the population of frogs as the frogs are present as tertiary consumers in the pond food chain. These frogs will feed upon mosquitoes, and limit their population.
Answer:
E. A, B, and C are all correct.
Explanation:
Microevolution is an evolutionary change that is said to occur on a small scale within a population of species over a short period of time. This can be seen in the case of the population of alpine plants. The change is within the population.
Genetic drift, by definition is the change in the allele frequencies, as can be seen in the alpine plants, which is brought about by a bottleneck effect. In order words, bottleneck effect occurs when a population size is reduced drastically as a result of environmental events such as landslide, that can be seen in the case of alpine plants. This genetic drift example randomly selects the surviving individuals in this microevolution.
