Co-evolution

Explanation:

A series of reciprocal adaptations in predator and prey populations describes co-dependence or co-evolution

In co-evolution, two species which are in association evolve together due to their relationship Both the species have different ancestryInteractions exhibited by co-evolution are: host parasite interaction, prey predator association, evolution of long proboscis in insects for taking nectar from flowers Predation is a very short term behavior in which two different species interact with each other for the demand of energy, one is prey and the other is predatorFor successful predation, predator wants minimum energy investment and maximum energy Increase in prey population in any given area attracts predator population, hence population of predator also increases in that areaIncrease in predator population results in decrease in prey population after some time decrease in prey population leads to decrease in predator population also
