In the context of factors limiting population growth, how can high population density be harmful to a population?
A
It always increases the per-capita availability of resources, leading to higher birth rates.
B
It decreases the spread of infectious disease by reducing contact among individuals.
C
It eliminates density-dependent limiting factors, so population growth becomes unrestricted.
D
It can increase competition for limited resources (e.g., food, space, and nesting sites), reducing survival and reproductive success.
Verified step by step guidance1
Understand that population density refers to the number of individuals of a species per unit area or volume.
Recognize that high population density means many individuals are living close together, which can intensify competition for limited resources such as food, space, and nesting sites.
Recall that density-dependent factors are those whose effects on the size or growth of the population vary with the population density; these include competition, predation, disease, and waste accumulation.
Analyze how increased competition due to high density can reduce the availability of resources per individual, leading to lower survival rates and decreased reproductive success.
Conclude that high population density can be harmful because it amplifies density-dependent limiting factors, thereby slowing population growth rather than promoting it.
