Class 12 Biology Organisms and Populations Population interaction

Population interaction

Interspecific interactions arise from the interaction of populations of two different species.

Interspecific interactions could be beneficial, detrimental or neutral to one of the species or both.

Both the species benefit in mutualism and both lose in competition in their interactions with each other.

In both parasitism and Predation only one species benefits

The interaction where one species is benefitted and the other is neither benefitted nor harmed is called commensalism.

In amensalism on the other hand one species is harmed whereas the other is unaffected. Predation, parasitism and commensalisms share a common characteristic– the interacting species live closely together.
