The population of mice in a local forest ecosystem has recently died out due to disease. in the past, these mice were the main predators of the forest beetles. what is the best prediction about what will happen to the beetles? a) the drop in the mouse population will lead to a drop in the beetle population. b) the drop in the mouse population will lead to no change in the beetle population. c) the drop in the mouse population will lead to an increase in the beetle population. d) the increase in the mouse population will lead to an increase in the beetle population.

 C)  The drop in the mouse population will lead to an increase in the beetle population.

The drop in the mouse population will lead to an increase in the beetle population. Since the mice are the beetles predator, when there are fewer mice, there will be more beetles.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

i think the answer is c hope this
