What are the possible impacts on the limiting factors that determine population size of an extended period of lower than normal rainfall?

An extended period of lower than normal rainfall can significantly impact the limiting factors of population size, particularly in terms of resource availability. Reduced water supply can lead to diminished plant growth, affecting food resources for herbivores and, consequently, predators that rely on them. This can result in decreased reproductive rates and increased mortality, ultimately leading to population decline. Additionally, competition for the scarce resources may intensify, further exacerbating the stress on populations already affected by the drought.
