The following picture shows ethidium bromide-stained DNA bands revealed by gel electrophoresis of the same circular DNA digested in three different tubes containing the following restriction enzyme(s): EcoRI only, BamHI only, or a mixture of the two enzymes. The arrow represents the direction of electrophoresis. (FYI, a restriction enzyme digests DNA by cutting both strands of a specific, short DNA sequence it recognizes.) How many EcoRI and BamHI site(s) are present in this circular DNA

answerscaffolding proteins;

answer;

a. sheep consumption efficiency would be reduced.

explanation;

-trophic efficiency is a measure of how much energy occurs at one level divided by the energy at the level immediately below it . trophic efficiency incorporates three types of efficiency:

-the proportion of available energy that is consumed (consumption efficiency).   it is the proportion of the available biomass that is ingested by consumers.

-the proportion of ingested food that is assimilated (assimilation efficiency).

-the proportion of assimilated food that goes into new consumer biomass (production efficiency).

-in this case, the grasshoppers would affect sheep by reducing the proportion of the available biomass that is ingested by the sheep.
