The interaction, in which one organism is benefited and the other is neither harmed nor benefited, is called

  • A.Parasitism
  • B.Camouflage
  • C.Commensalism
  • D.Competition

Answer: C

The interaction is commensalism.

In commensalism one species benefits and the other is neither helped nor harmed: for example, an orchid growing on a tree gains a place in the light without harming the tree, and cattle egrets feed on insects disturbed by grazing cattle.

In parasitism one benefits at the other's expense, and in competition both are harmed. Camouflage is an adaptation for concealment, not an interaction between two species.
