In general in which direction do convection cells in earth's atmosphere move heat around the planeta. clockwise among the jet streamsb. from the equator toward the polesc. from the surface to the upper atmosphered from east to west, among the westerlies

true is the final answer!

the answer is "a.) well–developed vascular system."

explanation:

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.
