Will give brainliest! an estuary ecosystem has been damaged by pollution and sediment runoff. what types of factors should be considered when designing a plan for the ecosystem's recovery? a. abiotic factors from the estuary only b. biotic factors from the estuary only c. both abiotic and biotic factors, but only from the estuary d. both abiotic and biotic factors, from the estuary and the surrounding area

D both abiotic and biotic factors, from the estuary and the surrounding area.

Because of the problem stated ( sediment runoff and pollution) it would need to be taken into account what actually caused the problem. I would assume the pollution is a non point source and would come from the surrounding environment. Sediment runoff is not necessarily  from outside of the estuary but it also would need to be taken into account to help the estuary become healthy again. 

Ithink all of these events
