What is the typical life cycle sequence of a nematode?

The correct answer describes the typical life cycle of a nematode as consisting of an egg stage, followed by four distinct larval stages, and culminating in the adult stage. This life cycle is common among many nematodes and emphasizes the developmental progression that these organisms undergo.

The sequence begins with the egg, which is laid in soil or within a host organism, depending on the species. After hatching, the nematode enters a larval stage, and it typically goes through several molts, transitioning through four larval stages before reaching adulthood. Each larval stage is crucial for the growth and development of the nematode, as it undergoes significant morphological changes and prepares for reproduction.

This life cycle highlights the complexity of nematodes and underscores their adaptability to various environments, which can help in understanding their roles as pests or beneficial organisms in agricultural settings and ecosystems.
