What change is likely to occur in a population of beetles that suddenly faces predation from an invasive species of frogs? the beetles' minimal viable population will increase. the beetles' minimal viable population will decrease. the carrying capacity of beetles will increase. the population density of beetles will decrease.

The population density of beetles will decrease.

Population density is the measure of number of individuals that makes up the population, living in a defined area. Invasive frog species is a predator for population of beetles, which is acting as a limiting factor for the growth of beetle population. Therefore, population density of beetles will decrease.  

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
