Solution
The correct option is B competitive release
A species whose distribution is restricted to a small geographical area due to the presence of a competitively superior species, is found to expand its distributional range dramatically when the competing species is removed. This phenomenon is referred to as competitive release.
Joseph Connell demonstrated competitive release with his study on two barnacle species, Balanus and Chthamalus, that competed for the same space on the rocky sea coasts of Scotland. Barnacles are sessile organisms that attach permanently to surfaces like rocks, bodies of whales, etc.
Connell documented that the larger Balanus, which normally occupies the intertidal zone, excluded the smaller Chthamalus from that region. When he experimentally removed Balanus, Chathamalus was able to colonise the intertidal zone. The experimental removal of Balanus allowed Chthamalus to undergo competitive release.
Resource partitioning is a mechanism evolved when more than one species compete for the same resource in nature. It promotes co-existence and reduces the intensity of competition. For example, five closely related species of warblers living on the same tree were able to avoid competition and could co-exist due to behavioural differences in their foraging activities.
Predation is a type of population interaction where organisms belonging to one species (the predator), captures, kills and eats organisms belonging to another species (its prey). One organism is harmed while the other one is benefitted in this type of population interaction. E.g: Tiger preys on deer
Parasitism is a type of population interaction between two living species in which one organism (the parasite) lives and derives nutrition from another specific organism (the host).
