When many plants grow in a crowded space where resources may not be sufficient to support all of them, some plants may die from a lack of sunlight, water, or nutrients.

Competition

Explanation:

The plants are competing against each other for the resources they need for survival. The other three answers involve different plants interacting with each other and the question does not mention interactions between them, meaning it's basically referring to survival of the fittest.

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i

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.
