Describe how population density can affect the interactions between individuals within a population.
Instructor solution
Population density refers to the number of individuals per unit area or volume. High population density can lead to increased competition for resources such as food, water, and shelter. It can also increase the spread of diseases and lead to more social interactions, which can be either positive (e.g., cooperative hunting) or negative (e.g., territorial disputes). Conversely, low population density might reduce competition and disease spread but can also make finding mates more difficult.
