Compare and contrast the process of digestion in cindarians and echinoderms

Answers

Some of the major difference in the digestive system of Cnidarians and echinoderm are

Cnidarians have an incomplete digestive system specifically extracellular digestion occur, where enzymes break down the food particles are degraded by enzymes and absorption occur in its gastrovascular cavity.

While in echinoderms, the digestive system may vary depending on types of species and need of their food types.

They use of tube feet to reach to their food sources and move their mouth area toward the food. Their digestive system relatively simple when compare with human.

What are the differences between cnidarians and echinoderms?

In Cnidaria only have gastrovascular cavity, diploblastic, presence of stinging cell, Hydrostatic skeleton etc.

In Echinoderm have triploblastic, water vascular system with unique characteristics, calcareous endoskeleton etc.

Echinoderms have no excretory or respiratory systems.
