I think it's cool that they both are carnivorous. They get their energy from the sun, like all plants, but they get nutrients from insects. Carnivorous plant grow in places where there are not a lot of nutrients in the soil. Sandy places don't have many nutrients.

I like to take my college classes to a bog north of Milwaukee. The water there is very acidic. bacteria don't grow well in the acidic water, so dead plants don't rot well. That means that the nutrients in the dead plants don't get returned to the water. Pitcher plants grow there in clumps that stick out of the water. The pitcher plants have hairs that grow pointing into a pool of water inside the "pitcher" formed by their leaves. Insects crawl in, but they can't crawl out. Plants secrete enzymes into the water that dissolve the bugs. Then the plant dissolves the nutrients.

Can you find any other carnivorous plants? If you were designing a plant to catch bugs, what would it look like? Thanks for asking,

There is nothing truly unique about these plants. They are all carnivorous plants in that they eat insects in order to get nitrogen and phosphorous that they can't get from the soil, but there are other carnivorous plants in the world than these (for example, the pitcher plant lifestyle has evolved at least twice in different groups of plants).
