What are the modes of nutrition of phylum aschelminthes?

Phylum Aschelminthes, also known as pseudocoelomates, primarily exhibit a heterotrophic mode of nutrition, meaning they obtain their food from other organisms. Most members are either free-living or parasitic, feeding on organic matter, microorganisms, or host tissues. They utilize a complete digestive system, allowing for efficient digestion and absorption of nutrients. Examples include rotifers, nematodes, and other related groups that have adapted to various ecological niches.
