ANSWER

There are five types of interaction between different organisms in an ecological communities. These are competition, commensalism, mutualism, parasitism and predation.

Competition is a type of interaction in which both the species are negatively affected. In this, the animals compete for the same food. For example, lions and leopards.

In commensalism, one species is benefited while other is neither harmed nor benefited. For example, cattle egret and cattle.

Mutualism is a type of interaction in which both the species are benefited. Lichen shows mutualistic interaction between fungus and algae.

Parasitism is a type of interaction in which one species is benefited while other is harmed. For example, tapeworm and man. In this, tapeworm is benefited and man is harmed.

Thus, the correct answer is option A.
