2) what type of nutrition do euglenids have
Euglenid As with other Euglenozoa, the primitive mode of nutrition is phagocytosis. Prey such as bacteria and smaller flagellates are ingested through a cytostome, supported by microtubules. These are often packed together to form two or more rods, which function in ingestion, and in Entosiphon form an extendable siphon. Most phagotrophic euglenids have two flagella, one leading and one trailing. The latter is used for gliding along the substrate. In some, such as Peranema, the leading flagellum is rigid and beats only at its tip.
Food pyramid (nutrition) These foods provide complex carbohydrates, which are an important source of energy, especially for a low-fat meal plan. Examples include corn, wheat, pasta, and rice.
