Pls help asap, will give brainliest for the best answer :)

b

Explanation:

Because of there are a few grass eating animals and a lot of grass what the point. But a ecosystem needs varaity of producers and consumers to keep it balanced.

Ecosystem B

because of the

teeming forests, cities that reuse and recycle and exist in harmony with the surrounding environments which are considered sustainable ecosystems.

what image you forgot to include it.

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.
