There are various compensatory responses of plants to animal herbivory. Sometimes,plants produce more biomass and seeds,increase growth rate and enhence their fitness. The factors affecting plant compensation are both endogenous and exogenous. Endogenous factors include:photosynthetic enhancement,reallocation of available assimilates,changes in canopy architecture and leaf morphology and delay of senescence following defoliation.Exogenous factors contan: nutrient availability,intensity and timing of defoliation, distribution of animal,and other environmental stressed.Therefore, there is a limitation of plant compensation.
