Ascaris, a type of parasitic roundworm, requires a digestive tract to efficiently break down and absorb nutrients from its host's food. The digestive system allows it to process the organic matter consumed in the host's intestines, enabling it to thrive and reproduce. Additionally, the digestive tract facilitates the elimination of waste products, which is essential for the worm's survival within the host environment. Overall, the digestive tract plays a crucial role in the parasite's life cycle and nutritional needs.

Why does an earthworm require a muscular digestive tract when an ascaris does not?
An earthworm requires a muscular digestive tract to effectively process and grind the organic material it consumes from the soil, facilitating nutrient absorption. The muscular contractions help break down the food as it moves through the digestive system. In contrast, an ascaris, which is a parasitic roundworm, absorbs nutrients directly from its host's intestinal contents, making a complex muscular digestive system unnecessary for its survival. As a result, ascaris has a simpler digestive structure tailored to its parasitic lifestyle.
