Competitive occurs when the competing species is no longer present. a. exclusion b. release c. expulsion d. none of the above

The correct answer is B. release

Explanation:

In ecosystems, competition occurs as different organisms or species need the same limited resources such as water, territory, food or shelter and therefore compete for it, this includes competition within species and also between them. This type of interaction often leads to the disappearance of one of the organism or species interacting, which is regulated by the competitive exclusion principle that states to species competing cannot coexist. Additionally, once one of the competing species is no longer present competitive release occurs, this implies the competition ends and the remaining species can access the resources more fully. According to this, competitive release occurs when the competing species is no longer present.
