Resource partitioning
prevents competitive exclusion, allowing the coexistence of several species using the same limiting resource
Character replacement
ionary relationships among animals; systematic attempts to develop models of animal classification →modification of the interacting species by selective adaptation →character displacement is thought to be an evolutionary response to interspecific competition
Exclusion
→replacement of one species by another has a competitive advantage evolutionary relationships among animals; systematic attempts to develop models of animal classification3 outcom →2 species competing for the same resource/s cannot coexist →leads to extinction of species
