Insectivorous plants prepare food by themselves, but they lack some of the vital nutrients such as nitrogen since they grow in soil where nitrogen is deficient. They eat some insects and thus make up for these nutrients. Hence they are said to be partial heterotrophs.

Insects are eaten by insectivorous plants to compensate for the deficient nutrients. An insect body has to be broken down before its nutrients can be absorbed into the plant. Carnivorous plants enzymes which help to break down the insect body and release nutrients.
