What would cause these population growth parameters to chang

What would cause these population growth parameters to change? Please help..having hard time understanding concepts. Please answer all parts. do not be alarmed by the number of figures and graphs below. These are for reference. Thank you for your help!!

question: based on all the graphs below in general, what are some factor that may cause changes in births, deaths, per capita population growth rate, and carrying capacity? It does not necessarily need to be exactly for those situations in the graphs

Questions Based upon what you\'ve seen above, what do you think can cause each of the following population growth parameters to change: 1. Births (b) 2. Deaths (d) 3. Per capita population growth rate (r), which is also calculated as (b-d) 4. Carrying capacity (K)

Solution

Birth parameter of a population that can change due a change in the carrying capacity i.e. the number of people, animals, or crops which a region can support without environmental degradation of that area or change in the population due to death or migration.
