Contrast the different ways bromeliads and pitcher plants acquire nutrients from animal sources.

Answer:

By collecting rainwater in their leaves, bromeliads create mini-ecosystems that house other small animals. When they die, these organisms decompose and the bromeliad benefits from the nutrients. Pitcher plants, meanwhile, actively trap insects and other small animals in their pitchers. The bromeliads are an example of mutualism while pitcher plants are predators.
