What happens to the population density and competition if the birth rate decreases? The birth rate would increase is the population density competition increased. Hope I helped.
The population density and the competition decreases in the population.
Explanation:
Population density may be defined as the number of individuals people living in an area per square kilometer. Birth rate is the umber of individuals born per 1000 in a year.
Population density is directly population to the birth rate. Since, the birth rate decreases the number of individual decrease and population density will decrease. Competition is high in a population if the number of individuals are large. Here, the birth rate decreases so the competition will also decrease as the number of individuals will decrease in the population.
Thus, competition and population density decreases if birth rate decreases.
