As the lines get closer that means that the elevation is getting higher and that is were the mountain or hill starts.
You are studying two species of tree frog. The two species are found on two different islands, separated by 200 km of ocean water. Species A lives on very light-colored rocks and species B lives on dark-colored trees. Which process is most unlikely to be affecting allele frequencies in the population?
a. Gene flow between populations
b. Genetic drift
c. Natural selection
d. Mutation rates
Answer:
a. Gene flow between populations
Explanation:
Gene flow between two populations occurs when one or a few members of one population migrate into the other and interbreed in the new population. This process adds some new alleles to the new population. In the given example, two populations of a tree frog are separated by 200 km of ocean water. Therefore, the frogs of one population would not be able to migrate into the other population and interbreed. So, gene flow can not affect the allele frequencies of these two populations.
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up
