Question 2 Some grassland ecosystems in Texas have evolved to depend on periodic 9 points
fires to return nutrients to the soil. Biologists have recommended starting
monitored "control burns every 3 to 4 years and they have observed
greater diversity in plant and animal life following these control burns".
What natural process are the biologists attempting to imitate?
Biomagnification
Succession
Population bottleneck
O Species extinction

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.
