Question

what is defined as \humans causing the feeding levels in an aquatic ecosystem to change in a negative way\?
biodiversity
cultural eutrophication
water treatment
bioaccumulation

Explanation:

Cultural eutrophication occurs when human activities, such as nutrient runoff from fertilizers or sewage discharge, increase nutrient levels in aquatic ecosystems. This leads to excessive algal growth, oxygen depletion, and disruption of feeding levels (trophic levels) in a negative way. Biodiversity refers to the variety of life forms. Water treatment is a process to make water suitable for use. Bioaccumulation is the gradual accumulation of substances in an organism.

Answer:

Cultural eutrophication
