What type of life cycle features the stages of egg, nymph, and adult?

The life cycle that features the stages of egg, nymph, and adult is characterized as an incomplete life cycle. In this type of life cycle, organisms develop through a series of gradual changes without a distinct larval stage or the dramatic changes associated with complete metamorphosis.

The egg stage is where the organism first begins its life. Upon hatching, the young emerge as nymphs, which resemble miniature versions of the adult but are not fully mature. As they grow, nymphs undergo several molts, gradually developing into adults. This progressive development allows for a more continuous transformation, differing significantly from the structure of complete life cycles, which include distinct larval stages and a pupal state.

In summary, recognizing that the absence of a larval stage and the presence of a nymph phase leading to the adult form is what classifies this life cycle as incomplete is key to understanding this concept.
