Biologists performed an experiment with flies to examine the effects of population size on the maintenance of genetic variation and on egg-to-adult survival. From a large source population, they randomly assigned eggs to three experimental populations of size N, equal to 20, 60, and0100. For later generations, they collected N eggs from each population and moved them into identical vials that co0ntained f2re0sh me4d0ium. Th6e0y coun8te0d the number of adult flies that emerged and used tissue samples from the adults for genetic analyses. Genetic variation was measured by scoring alleles at several polymorphic loci and expressed as the average number of alleles at those loci. The results are summarized in Figure 1 and Figure 2 below.
Which other process appears to have substantially influenced the outcome of this experiment?

Herbivore ingests plant material with 1000 k j energy form producer and assimilated only 200 k J energy in their blood stream; additionally herbivore invests 120 k j energy in their maintenance. What is production efficiency of that herbivore?
