First one who answers gets the thing

A construction company recently filled in a local pond to build new houses. During
the following weeks, a local scientist noticed a decline in the mosquito population in
the area. The scientist wants to conduct a study that will measure the change in the
local mosquito population over a period of three months. Which research method
would give the scientist the best data for conducting his study?

A/ a collection device in the area that counts the number of mosquitoes caught
weekly.

B/ a three-month case study observing the behavior of animals that depend on
mosquitoes for food.

C/ a controlled lab experiment with mosquitoes that limits water access for the
experimental group.

D/ a survey asking residents about their observations of the local mosquito
population.

C/ a controlled lab experiment with mosquitoes that limits water access for the experimental group.

Explanation:

The scientist is looking for what could cause the decline in the mosquito population and if it is due to the filling of the local pond. To best conduct research on this topic would be to experiment with mosquitoes and their responses with limited water access. It has the two variables, the mosquitoes and water. This is the most effective way of determining his study.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
