Question

The following graphs show the sizes of four different populations over a period of time. Write a sentence summarizing what each graph shows.

Answer 1

In graph 1 the population has gradually increased in number, graph 2 shows the population had a gradual increase and a sudden drop in the number, graph 3's population has multiple times in change and finally graph 4 shows a steady rate in the population.

Answer 2

Answer:

Population may be defined as the group[ of the individuals of the similar species that can reproduce among themselves. Different population shows different growth rate.

Graph 1 shows the steady rate of population. The population increases with respect to time as the factors are abundant in this case.

Graph 2 shows the sharp increase in the size of a population for the particular time. As the factors become limited, the population shows sharp decline in its growth.

Graph 3 shows the sharp increase and sharp decline in this population growth with time. The growth of population has been fluctuated multiple times due to the presence and absence of the growth and other factors.

Graph 4 shows the constant population with respect to time. The population neither increases nor decreases in this graph.
