With the decline in the population of fig species it was noticed that the population of wasp species also started to decline. What is the relationship between the two and what could be the possible reason for decline of wasps?
The relationship between the plant and pollinator is called mutualism.
Fig depends on wasp for pollination, and wasp depends on fig for
food and shelter. With the decline in population of figs, wasp loses its source of food and shelter.
