Answer:
Answer is B What environmental factors caused certain wetlands plants to become stressed enough to die?
Step-by-step explanation:
What environmental factors caused certain wetlands plants to become stressed enough to die? This is a start. Chances were it was not just one factor. Salinity may have played a role, but what else? In fact, they concluded that under severe drought conditions and other interacting factors, plants became stressed or died because of low soil moisture combined with physical and chemical changes in the soil that likely resulted in soil oxidation, soil acidification and metal toxicity. Somewhat elevated salinity and fungal pathogens may have played a secondary role in salt marsh dieback.
