This is because toxins are ingested by organisms and accumulate in the fatty tissues. Theses toxins then become more concentrated in successive trophic levels of a food web biological magnification. Magnification occurs because the biomass at any given trophic level is produced from a much larger biomass ingested from the level below and therefore, top-level carnivores tend to be the organisms most severely affected by toxic compounds.
Answer:
4 ATP molecules
Explanation:
Normally, about 11 ATP molecules are generated as the result of Beta-Oxidation of saturated fatty acid in Kreb's Cycle. But the total removal of acetyl-CoA under certain aerobic condition decreases the overall yield and approximately 4 ATP molecules comes out from each removal of acetyl-CoA.
We know, only 10% of energy transferred from each trophic level. Plant can capture 1% energy from the sun. According 10% law only 10% energy transfer to next level. Thus if plant has 1%- trophic level 2 will have 0.1%; then third trophic level will have 0.01% and we human if we are on fourth level then we will have 0.001%.
Thus correct answer is 0.001%.

Whether a particular independent variable influences the dependent variable Test whether the true value of the parameter estimate is zero. The higher the value of the t-statistic, the smaller the value of the regression coefficient is zero.</span>
