What is density dependent and what problems do they cause?

Density-dependent factors are variables that affect population growth in relation to the population's density, such as competition for resources, predation, disease, and waste accumulation. As population density increases, these factors can lead to decreased birth rates, increased death rates, and ultimately population decline. Problems arising from density-dependent factors include resource depletion, increased conflict among individuals, and higher susceptibility to epidemics, which can destabilize ecosystems and threaten species survival.
