In which of the following scenarios is a resource likely to be degraded as a result of the "tragedy of the commons"? A farmer plants a monoculture instead of a variety of crops.
A mining company buys land from native communities for exploration.
A rancher uses dogs to deter wildlife from preying on his livestock.
An oil drilling company allows oil to seep into the oceans at an offshore rig.

answer; incomplete dominance;

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.
