More Information

☆ Types of biotic interaction :-

• Mutualism :- When both species benefit. Example- In Lichens, Algae provides food by photosynthesis and Fungi provides shelter, thus both get benefits.

• Commensalism :- When one species benefits, the other is unaffected. Example- cow dung provides food and shelter to dung beetles. The beetles have no effect on the cows.

• Amensalism :- One species is harmed, the other is unaffected. Example-as in the above question.

• Predation and parasitism :- one species benefits, the other is harmed. Example-Predator kills and eats prey; Virus(Parasite) causes harm to the host.

• Competition :- both species are harmed by the interaction. Example-Two species live in the same niche are in competition.

• Neutralism :- There is no net benefit or harm to either species. Example- Two same species inhabiting the same space(large) and using the same resources(large).
