As a result, algal blooms are more common.Algal mats on the sea bottom limit sunlight and alter the amount of dissolved oxygen in the water. Additionally, some algae produce toxic compounds that can enter shellfish. Furthermore, the decomposing algae produces a strong odor. Which statements below correctly match the outcomes to their effects on value of the ecosystem? Check all that apply.
_____ Aesthetic value is lost because the algae makes the beach ugly and smells terrible. _____ Indirect economic value is lost because fisherman cannot catch their usual fish. _____ Direct economic value is lost because the toxic shellfish cannot be eaten. _____ Aesthetic value is gained because the algae could be used for biomass. _____ Direct economic value is lost because the properties near the beach aren’t as desirable.
