Which statement is the most accurate about red tide?

The most accurate statement about red tide is that the toxins from red tide bioaccumulate in oysters and biomagnify in people. Red tides are caused by harmful algal blooms, particularly by certain species of dinoflagellates, which can produce toxins that are harmful to both marine life and humans. These toxins can accumulate in marine organisms, such as oysters, clams, and other filter feeders, a process known as bioaccumulation. When humans consume these contaminated shellfish, they may experience serious health issues, as the toxins biomagnify through the food web, increasing in concentration at each trophic level. This means that the risks associated with red tide extend beyond marine ecosystems and directly impact human health through seafood consumption.
