Genetic variation in a new generation of organisms is the result of..
A. Sexual reproduction involving one parent
B. Sexual reproduction involving two parents
C. Asexual reproduction involving one parent
D. Asexual reproduction involving two parents

B

Explanation:

B because sexual reproduction involve 2 people. Asexual reproduction only involves 1 parent. Genetic Variation is used to describe the variation in the DNA sequence in each of our genomes.

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.
