Answer 1

Answer:

B.  0.10 - 0.20 = 0.10.

Step-by-step explanation:

100/1000 = 0.10 of the population were born , and

200/1000 = 0.20 of the population died so it is:

0.10 - 0.20 = 0.10.

Answer 2

Answer: B

Step-by-step explanation:

The total population was initially 1000 individuals. In this population, a total of of 100 new individuals were born over the course of one year. The proportion of new individuals that make up the population is 100/1000 = 0.1

Since they were added, then it is positive and it is a gain for the population.

A total of 200 individuals also died over the course of one year. The proportion that died = 200/1000 = 0.2. This would be negative because it is a loss for the population.

The population growth rate will be gain - loss. This becomes

0.1 - 0.2 = -0.1
