Solution
This behaviour is called as competition which is usually in the form of fighting.
Individual animals frequently compete for food or opportunities to mate, for example, it is seen as pecking order in the chickens.
Too much competition among the members in the group hampers the cohesion of the group, consequently, many animals minimise the extent of within-group conflict by displaying signals of dominance.
