Which of the following best describes the function of the human nervous system? A.
The nervous system gathers, interprets, and responds to information about the body's internal and external environment.
B.
The nervous system transports oxygen and nutrients to the cells of the human body through a system of nerve cells.
C.
The nervous system breaks down large food molecules into smaller nutrients so that they can be transported around the body.
D.
The nervous system removes waste products from the human body through the excretion of sweat and urine.

A.the nervous system gathers,interpret and respond to information about the body's internal and external environment

Explanation:

the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body

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.
