Apopulation 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

The two possible reasons are emigration or increase in death rate. The population began with 67 and decreased to 53. This may have occurred primarily due to two main reasons i.e. increased death rate due to some problems in the habitat of the frogs which is the pond.
