The horizontal axis of the graph represents time, from 65,000 BCE (Before Current Era) to the present. Periods of 5,000 years are separated by vertical lines.
The vertical axis shows the total size of the world population, which has grown spectacularly over the period. Between 50,000 BCE and the present day, the number of human beings has risen from around 600,000 to 6.5 billion, a ten thousand-fold increase.
If that helps :)
Answer:
The most notable difference is that the zombie population in the game grew, while the scientist's population of disease cells decreased. Second, the decay rate of the cells is much faster than the growth rate of the zombies in the game levels. The rate of cell decay is 50%, while the rate of population growth is 5% per game level. That means the scientist’s graph will curve downward more sharply than the zombie population graph curves upward.
