Erforrásversengés

Erforrásversengés, often translated as "resource competition," is an ecological concept describing the struggle between organisms for limited resources. These resources can include food, water, sunlight, shelter, or mates. When the demand for a resource exceeds its availability, competition arises. This competition can occur between individuals of the same species (intraspecific competition) or between individuals of different species (interspecific competition).

Intraspecific competition can be particularly intense as individuals within a species share the same resource requirements and ecological niche. This can lead to density-dependent population regulation, where population growth slows as the population size increases due to heightened competition. For example, in a dense forest, young trees may compete fiercely for sunlight and nutrients, with weaker individuals often failing to survive.

Interspecific competition occurs when different species require the same limited resources. This can have significant impacts on the populations and community structure of an ecosystem. If one species is a more efficient competitor, it may outcompete another species for a vital resource, potentially leading to the displacement or even extinction of the less successful competitor. This is a fundamental principle in evolutionary biology and ecology, driving adaptation and niche partitioning, where species evolve to utilize resources in slightly different ways to reduce direct competition. Understanding erforrásversengés is crucial for comprehending ecological dynamics, population control, and the distribution of species.
