A mutualistic symbiotic relationship is the one in which the two species lives in close association and both of the species obtains the benefit of living together.
Cattle depend on microorganisms in their digestive tract to digest the cellulose in their diets is the example of mutualistic symbiotic relationship. This is due to the fact that cellulose is a biomolecule which is obtain in leafy diets of the cattles. This is difficult to digest by the digestive system of the body of these cattles therefore, the function of digestion is performed by the microbes present in the digestive tract. Both of the organisms attains nourishment after this process.
Answer: 2. D. more likely to have a digestion tract than to have a gastrovascular cavity.
The complex animals are expected to have a complex digestive system. The gastrovascular cavity secretes digestive juices which aids in the process of digestion.
