a population of frogs in a pond began with 67 individuals. over one year, the population changed to 53. which are two possible reasons for the change within the frog population? emigration or increase in death rate emigration or increase in birth rate immigration or decrease in death rate immigration or increase in birth rate

Answer

Brief Explanations:

Emigration means frogs leaving the pond, reducing the population. An increase in death - rate also reduces the number of frogs. Immigration and increases in birth rate would increase the population, not decrease it as observed here.

Answer:

emigration or increase in death rate
