which of the following is the result of biological magnification?
a. toxic chemicals in the environment pose greater risk to top level predators than primary consumersb. populations of top level predators are generally smaller than populations of primary consumersc. the biomass of producers in an ecosystem is generally higher than the biomass of primary consumersd. only a small portion of the energy captured by producers is transferred to consumerse. the amount of biomass in the producer level of an ecosystem decreases if the producer turn over time increases
