If you look at different sessile aniimals, you'll notice that they are generally filter feeders- they suck in nutrients from their surroundings. Those that are larger and can "pull in" more nutrients than others. Holometabolus insects do it because the larvae can eat and inhabit a different place than the adults so there is no competition for resources, like food. Lepidopterans are a good example, caterpillars eat leaves and plants while the adults pollinate flowers and drink nectar.
