Answer 1

Some plants eat insects because they don't get enough of nitrogen from the soil and to regulate the amount of nitrogen they eat insects. These plants are called Insectivorus plants.

The insect falls into the pool of fluid and is consumed by the plant. Pitcher plants are famous for their flesh-eating ways, and they rely on slippery surfaces to trap their prey. Its pitcher-shaped traps are made from rolled up leaves, and secrete nectar from their rims to entice their prey.
