Explanation:

Bioaccumulation is defined as the increase in concentration of a substance(s) in an organism or a part of that organism. The affected organism has a higher concentration of the substance than the concentration in the organism's surrounding environment. For the second statement: Microorganisms eat pesticide infected things. Invertebrates eat hundreds of the microorganisms and plants infected with the pesticides, accumulating a pretty large amount of the toxin in them. The invertebrates are generally then eaten by larger invertebrates or amphibians, which ingest hundreds of similar organisms, accumulating an even higher concentration of toxins in their bodies. Then the fish eat hundreds of these organisms, accumulating the highest concentration of toxins in themselves.
