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%

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

they absorb it i think

not sure
