Carnivorous plants are great examples of biodiversity and evolution in action. This range of plants stalk their prey, setting traps to provide themselves the food and energy they need to grow. The plants evolved this way so they could thrive in waterlogged and nutrient deficient soils. Carnivorous plants spend most of their time in a vegetative state. However, Venus Flytraps are the exception, occasionally bursting into action before devouring their prey.
