Which of the following is not a problem in a small population?
Inbreeding
Preditation
Disease
Birth Rates
Answer:
in all honesty, they are all a problem. I would say the least likely not to be a problem is predation.
Explanation:
Smaller numbers mean you have fewer opportunities and choices to reproduce, hence inbreeding and birth rates (if the birth rates were low). any disease could then wipe out the population due to a lack of genetic diversity. So I would say preditation is your best bet

Decreasing first and then growing happening to the population because at every year 10.20 percent population is growing.
How can you figure out a population's growth rate when there are births and deaths?The net reproduction rate (r) is computed as follows: r = (births-deaths)/population size, or simply multiply by 100 to get in percentage terms. Because the population has grown so much, many more people have been added. When a population grows at a steady rate year after year, this is referred to as exponential growth.
Migration is the the number of immigrants minus the number of emigrants over a given time period, divided by the number of person-years lived by the receiving country's population during that time period. It is calculated as the number of net migrants per 1,000 people.
