Species of oak trees periodically have years of large acorn production, followed by years of lower acorn amounts. in years of plenty, squirrel populations will experience an increase due to increased food availability of acorns. then, squirrel populations will decrease after lower acorn abundance. this is an example of species of oak trees periodically have years of large acorn production, followed by years of lower acorn amounts. in years of plenty, squirrel populations will experience an increase due to increased food availability of acorns. then, squirrel populations will decrease after lower acorn abundance. this is an example of

This is an example of "Population Cycle"

In a population cycle, there is drop and rise in the population of species with time. Also this process of population drop and rise is repetitive in nature. Here in this case the series of events taking place are as follows:

a)Oak trees have large acorn production

b)With rise of acorn production, squirrel population increases owing to availability of food

c)Oak trees have lower acorn production

d)With decrease in acorn production, squirrel population decreases owing to reduction in food availability

If we plot the population cycle of two species i.e oak tree and squirrel on a graph, it results into two parallel sinusoidal graphs. The population of one species changes with the change in population of other species

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
