Answer

Correct Option is 1 and 3 only

(1) Commensalism: This is an interaction in which one species benefits and the other is neither benefitted nor harmed. For examples:Cattle egret and grazing cattle as well as Sea anemone and clown fish are the examples of Commensalism. (a) Cattle egret and grazing cattle, where egrets forage close to where cattle graze. As the cattle move, the vegetation insects come out. Otherwise it is difficult for the egrets to find and catch the insects. (b) Sea anemone and clown fish: The fish gets protection from the predators with the help of stinging tentacles of the sea anemone. The anemone has no any benefit. (2) Predation: Organism of higher trophic level (predator) feeds on the organism of lower trophic level (prey) is called predation. (3) Mutualism: it is an interaction between two living organisms, where both are equally benefitted. No one is harmed. For example, fig trees and wasp, lichen, etc.
