Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of a population. These factors include food availability, predation, disease, and space. When a population reaches its carrying capacity, or the maximum number of individuals that the environment can support, limiting factors prevent further growth by reducing birth rates, increasing death rates, or causing individuals to emigrate.
The biotic components within an ecosystem interact with each other through various relationships such as predation, competition, mutualism, and symbiosis. These interactions play a crucial role in shaping the structure and function of ecosystems. For example, predators help control prey populations, while mutualistic relationships like plant-pollinator interactions contribute to overall ecosystem stability.
