Two descriptions for a sub-atomic particle are listed below: description 1: revolves around the nucleus of the atom description 2: has the least amount of mass which sub-atomic particle or particles fit these descriptions? electrons only protons only electrons and neutrons protons and neutrons

Electrons only Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.

i would think it's dendrites

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.
