The relationship between numbers of different populations is based on the requirement, mode of nutrition, shelter, and habits of species. There are broadly three types of species interaction, first one is a positive interaction, second is negative interaction and the last one is passive interaction. In positive interaction both the species interacting are benefited. In negative interaction at least one species harmed. Examples of positive interactions are commensalism, mutualism, protocooperation, etc. Examples of negative interaction amensalism, competition, parasitism, predation, etc. Play Species Interaction or Inter Specific Animal Relationship quiz and know more about interspecific animal relationships or species interaction.
