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.
Does a jellyfish have a simple or complex digestive system?
Jellyfish have a simple digestive system. They have a digestive cavity with cells lining the wall that carry out the digestive function.
Why does ascaris need a digestive tract?
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.
What two body system are most visible in Ascaris?

What is the defence mechanism of phylum Nematoda?
Nematode parasites live in the digestive system of the host and so employ some mechanism to prevent being digested and prevent triggering an immune response. For example, Ascaris roundworms secrete a series of inhibitors to target digestive and immune-related host proteases, which include pepsin, trypsin, chymotrypsin/elastase, cathepsins, and metallocarboxypeptidases (MCPs). Ascaris inhibits MCPs by releasing a enzyme known as Ascaris carboxypeptidase inhibitor (ACI). This enzyme binds to the active site of MCP and blocks the cleavage of its own proteins by the host MCP
What is the scientific name of ascaris?
The scientific name of ascaris is Ascaris lumbricoides.
