N a certain ecosystem, hawks prey on mice. If the population of hawks gets smaller, what will happen to the population of mice?
A) It will grow larger, because there are fewer predators. B) It will grow smaller, because the mice rely on hawks for food. C) It will remain the same, because hawks do not affect mice.
A) It will grow larger, because there are fewer predators.
Explanation:
The hawk is a predator of the mouse. In this case, if the hawk population increases, the number of rat predators increases and this causes the rat population to decrease, due to an intense predatorism that hunts them. However, there comes a time when the population of mice will be so small that they will no longer be able to feed the hawks, who will starve to death, or migrate to a region where they have more food. As a result, the hawk population decreases progressively, allowing rats to reproduce and increase the population. Thus, the decrease in the population of hawks, decreases the number of predators of rats and allows the population of animals to grow.
Face validity of an instrument refers to the style of questions on an instrument that enables the respondents to determine the purpose of the questions by merely reading the questions is a TRUE statement.
<u>Explanation:
</u>
The purpose of the questions enumerated on a given instrument is often very easy to comprehend.
It allows the respondents to easily devise what issues or subjects are the questions associated with.
Once the respondents get an idea of what the questions are about, they can plan how to tackle them or otherwise just simply prefer to leave them.
The behavior that Thaddeus is showing above best illustrates
the planful problem solving. This type of problem solving is where an
individual is likely to focus on the problem given to him or her in which he or
she provides efforts in altering the situation.
