Competition is the type of association in which both the organisms suffer adversely.
Competition can be interspecific or intraspecific. Generally, the intraspecific competition is more intense.
Competition can be further classified into
a. Direct interference type: In this the interacting species directly inhibit each other as they come in direct contact with each other.
b. Resource use type: It results indirect inhibition when common resource is in short supply.
Competitive exclusion principle (Gause’s Principle): In the simplest form this principle states that a complete competitor cannot coexist.
Abingdon tortoise in Galapagos Islands became extinct within a decade after goats were introduced on the island.
Lotka-volterra model describes the outcome of competition between two species (coexist or eliminate) and it is based on logistic growth equation.
