A is true but R is false.
Insectivorous plants are also called as carnivores. Like all other plants, these plants are green and carry out the process of photosynthesis. They capture solar energy and prepare carbohydrates. But they eat insects to gain nutrients such as nitrogen. This is due to the fact that these plants grow in soils where nitrogen content is poor.
