The population of the bronx according to the 2010 united states census is approximately 1,400,800. assume 500,000 of the individuals living in this area are considered "at risk" for disease transmitted by the norway rat. if 500 existing cases of rat-transmitted disease were noted on november 17, 2008, what is the point prevalence for the disease?

it is prolly d and c and f

answergaba;

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.
