The results of experiments conducted by louis pasteur showed

a) that all cells come from preexisting cells
b) strong support for the theory of spontaneous generation
c) that all bacteria are unicellular organisms
d) strong support for the new cell theory

that all cells come from preexisting cells

Explanation:

Louis Pasteur postulate that all living cells come from preexisting cells. Cells are the basic unit of life. All living things are made up of cells that formed through division of the preexisting cells. The scientist cultured cells in a lab. After few days, the mass of cells had increased greatly.

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.
