1) D. Explanation: If the birth rate is larger than the death rate, then the population will grow (as long as it is not affected by immigration or emigration). If the death rate is larger than the birth rate, then the population will shrink (as long as it is not affected by immigration or emigration).
2) C. Explanation: Death and emigration are the common ways in which the population will decrease.
3) B
4) A
To get the answer to question 1, we need to compare the birth rate and the death rate. If the birth rate is larger than the death rate, then the population will grow. If the death rate is larger than the birth rate, then the population will shrink. It's important to note that these calculations are made without taking into account immigration or emigration, which can also impact population growth or decrease.
For question 2, we are asked to identify the common ways in which the population will decrease. The two common factors that contribute to population decrease are death and emigration. When individuals pass away or leave a particular area through emigration, it results in a decrease in the overall population.
