Mutualistic - Both the interacting organisms are benefitted from each other e.g. Lichens- Algae and fungi mutually help each other.
Competition - When two organisms belonging to closely related species/ unrelated groups compete for the same resources that are limiting both are losers , e.g. superior barnacle dominates and excludes the small barnacles / in some South American lakes visiting flamingoes and resident fishes compete for their common food (zooplankton) in the lake.
Parasitic - One of the two organisms is dependent on the other( host ) for nutrition and support / the host is harmed and the parasite is benefitted . e.g. Malarial parasite and human / Cuscuta on host plant .
Competition - When two organisms belonging to closely related species/ unrelated groups compete for the same resources that are limiting both are losers , e.g. superior barnacle dominates and excludes the small barnacles / in some South American lakes visiting flamingoes and resident fishes compete for their common food (zooplankton) in the lake.
Parasitic - One of the two organisms is dependent on the other( host ) for nutrition and support / the host is harmed and the parasite is benefitted . e.g. Malarial parasite and human / Cuscuta on host plant .
