Why does the pitcher plant use chemicals to turn its food into soup?

The pitcher plant is an insectivore plant that feeds on the insects. Although, it contains chlorophyll, and is capable of making food via photosynthesis, its habitat in the swamps makes it difficult for it to have access to minerals such as nitrogen. The nitrogen is obtained by it by digesting the insects by trapping them in the rolled leaves. The digestive enzymes are secreted by this plant, in order to digest these trapped insects. Since, it has no proper digestive system is present, these secreted enzymes turn the food into soup that can be easily absorbed.
