A farm on the edge of the forest ecosystem sprays the crops with insecticide, which kills the insects eating the crops. Some of the insecticides also gets on some of the caterpillars in the ecosystem
mentioned in the energy pyramid. Half of the caterpillars in the ecosystem die. How will that affect the
plant, chameleon, snake, and mongoose populations?

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.
