Which of the following limited factors would be directly affected by drought ? a. birth/death rate b. immigration c. available niche d. resource supply

The correct answer is D. Resource supply

Explanation:

In ecosystems, a limiting factor refers to a factor that regulates the growth of populations usually by limiting it, this includes natural disasters, predators, competition, among others. In the case of drought, this occurs as there is low or no rainfall and as a consequence, there is a shortage of water, plants and even animals that depend on rain or the resource supply for other organisms which represents an important limiting factor as with no or few resources populations cannot thrive. Thus, the limiting factor affected by drought is the resource supply.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
