If all of the detritus leaving the marsh is plant material, what percentage of all net primary production leaves the marsh as detritus each year?

I believe this problem has the following figure to go with (see attached pic).

Based from the table, we can calculate the percentage of net production leaving as detritus each year. Calculating:

(Detritus leaving marsh) * 100% / (Net grass production)

= 3671 * 100% / 6585

= 56%

idk im sorry.

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.
