Plants & Trees (Q&A)

Answer:

Some plants are carnivorous because the soil in which they live in is too poor in nutrients to sustain them for long. Such soil is generally found in acidic bogs and rock outcroppings. They have adapted through evolution to derive some or most of their nutrients but not energy from trapping and consuming animals or protozoans, typically insects and other arthropods. They require certain substances in the insects around them such as potassium, that are not present in the soil to produce flowers, which take quite a bit of energy to produce.
