Final answer:
The statement is false. As the density of a population increases, dispersal usually increases. Competition for resources leads to individuals dispersing in search of better conditions.
Step-by-step explanation:
The statement is false. As the density of a population increases, dispersal usually increases rather than decreases. This is because when a population becomes more crowded, individuals are more likely to compete for resources such as food, water, and space. As a result, some individuals will disperse or move away from the crowded area in search of better conditions.
For example, imagine a population of birds in a forest area. As the population increases, the competition for nesting sites and food sources may become intense. Some birds may choose to disperse and establish new territories in less crowded areas to avoid the competition. This dispersal helps to reduce the population density in the original area.
In summary, as the density of a population increases, dispersal usually increases as individuals move away from crowded areas to find better resources and reduce competition.
