Answer :
Answer: B) Certain species of mosquitoes are vectors for various diseases, such as malaria, dengue fever, and Zika virus, transmitting pathogens from one host to another through their bites.
Explanation: Though most mosquitoes mainly feed on nectar for the majority of their lives, (thus making them pollinators to some extent) female mosquitoes feed on blood in order to nourish their eggs and young. As a result, some species of mosquitoes serve as vectors for a variety of diseases, such as those mentioned in answer choice B. They're able to transmit diseases by transferring pathogens from an infected individual to a healthy one through bites, resulting in the transmission of sickness.
Most mosquitoes are parasitic or primary consumers, not predators. Thus, choice C is inaccurate since most mosquitoes do no hunt aquatic insects. The choice is also inaccurate since it states that mosquitoes have no impact on human health, when they clearly serve as transmission vectors for a variety of deadly diseases.
Choice A is also incorrect since its inaccurate to state that mosquitoes "have minimal impact on human health." Hundreds of thousands of people die from malaria alone on an annual basis. The number one vector of malaria is the mosquito. Thus, t would be completely wrong to deem them having a "minimal impact."
Choice D is incorrect because they simply do not fertilize soil through any means. They do pollinate crops, but they absolutely do not fertilize the soil.
