‘Two closely related species competing for same resources cannot co-exist indefinately’. This law is also called

The statement you provided reflects the competitive exclusion principle, which states that two species competing for the same limiting resources cannot coexist indefinitely. This principle, first formulated by ecologist Georgyi Gause in the 1930s, is foundational in ecology and helps explain many aspects of species distribution and community structure.

When two species compete for exactly the same resources, one is likely to outcompete the other, leading to the extinction of one species in that particular habitat. This principle implies that for two species to coexist in the same ecosystem, they must occupy different niches or find ways to utilize the resources differently. The competitive exclusion principle highlights the importance of biodiversity and stable ecosystems, as it demonstrates how competition can lead to niche differentiation and evolutionary changes within populations.
