In Dr. Shoba Iyer's presentation "Introduction to Toxicology" she identified the pathway for chemicals to enter and exit our bodies. Some chemicals stay in our bodies for just hours (water soluble) and others stay in for days/months/years (fat soluble). Which of the following is the correct order? Distribution, Metabolism, Absorption, Excretion

Absorption, Distribution, Metabolism, Excretion

Absorption, Metabolism, Excretion, Distribution

All of the above

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.

can i pls have the choices?

where are there choices to this question?
