At 88 meters (289 feet), Landscape Arch is the longest natural arch in Arches National Park in Utah. Many geologists believe it is the longest natural arch in the world. This natural arch was produced by:
•heavy exposure to running water at the base of the rock
•erosion of softer minerals from the center of the rock
•excessive weathering caused buy heat and pressure on top of the rock
Or
•repeated exposure to wind on the lower parts of the rock

answer; convade;

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.
