If the mangrove trees in an area were removed, which of the following does NOT become a greater concern?

The correct answer is bioaccumulation because the removal of mangrove trees primarily impacts the physical and ecological attributes of the coastal ecosystem rather than directly influencing the concentration of pollutants in organisms. Bioaccumulation refers to the process by which certain toxic substances accumulate in living organisms over time, particularly in tissues. While mangroves play an essential role in filtering pollutants and providing a habitat for diverse species, their removal mainly affects habitat loss, coastal protection, and water quality rather than the accumulation of pollutants within organisms.

The other concerns related to the removal of mangroves are significant. For instance, the loss of habitat for various species is a direct consequence of deforestation, leading to decreased biodiversity. Increased coastal erosion occurs because mangroves act as natural barriers, stabilizing shorelines and reducing the impact of wave action. Lastly, decreased water quality can result from the lack of mangrove root systems that filter toxins and sediments from water, contributing to improved overall water health.
