Question

A constant rate of increase (rmax) for a population produces a growth graph that is J-shaped rather than a straight line. Why?

Answer 1

Answer:

Explanation:

The line graph illustrates the temperatures in London, New York and Sydney on monthly average and the table introduces the information about the annual hours of sunshine for these cities. The overall view is that London is always exceeded by the rest in both the temperature and the number of sunshine hours.

To specify, the line graph shows that in New York, the average temperature goes up slightly from 4.5 degree in January to 8 degree in March, before a more significant increase to the highest of 30 degree in July, followed by a drop to 5 degree in December. Similarly, in London, after climbing gradually from the lowest point of 9 degree to the highest of 23 degree in July, the figure stays unchanged in the next month and then fall to 9.5 degree in December.

On the contrary, in Sydney, the temperature decrease insignificantly from 25.5 degree in January to the lowest of 16 degree in July, before a gradual rise to 25 degree in December. Meanwhile, the table indicates that New York has the largest number of sunshine hours per year with 2535 hours, came after by Sydney and London with 2473 hours and 1180 hours respectively.

In conclusion, London is likely to be the coldest city because its annual hours of sunshine is less than two others.

Answer 2

Answer:

Because the growth rate is constant, that is, the population is constantly growing and not stagnant.

Explanation:

The J-shaped growth graph occurs because the population is changing size (growing) as this population has a constant rate of increase. If the population was stagnant, it was neither increasing nor shrinking in a given size. time interval, the chart would have a line shape.

In other words, we can say that at a constant rate of increase, the population is growing steadily, causing a displacement of the line presented by the map that takes the form of J.
