The Effects of Bioaccumulation on the Ecosystem

WebOct 15, 1992 · 1) Bioaccumulation in organisms may enhance the persistence of industrial chemicals in the ecosystem as a whole, since they can be fixed in the tissues of organisms. 2) Stored chemicals are not exposed to direct physical, chemical, or biochemical degradation. 3) Stored chemicals can directly affect an individual's health. WebLAB ACTIVITY Objective: PCBs, like DDT, are a POP that are a part of the “Dirty Dozen.” PCBs bioaccumulate and biomagnify in the same way as DDT does.

WebHow does biomagnification work? Lipid (lipophilic) or fat soluble substances cannot be diluted, broken down, or excreted in urine, a water-based medium, and so accumulate in fatty tissues of an organism if the organism lacks enzymes to degrade them. WebDecomposers as a group play a critical role in keeping ecosystems healthy. When they break down dead material and wastes, they release nutrients that can be recycled and used as building blocks by primary producers.
