As per the question, model of cell looks like a city where different buildings correspond to different organelles ( membrane bound subcellular compartments like nucleus, golgi complex, vacuole, endoplasmic reticulum).
Nucleus is a specialized membrane bound compartment that possesses the genetic material ( DNA) of the Eukaryotes ( like plants and animals).

Decreasing first and then growing happening to the population because at every year 10.20 percent population is growing.
<h3>
How can you figure out a population's growth rate when there are births and deaths?</h3>
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.
