How do cnidarians seize and eat faster organisms?
Consequently, how do cnidarians capture and consume food?
Cnidarians are carnivores, and some can also consume plant matter. They catch their food using their nematocysts or through filter feeding. Cnidarians digest their food using a primitive digestive system that contains no organs--they have a mouth (which also serves as the anus) and a gastrovascular cavity.
Similarly, what type of digestion occurs in cnidarians? Cnidarians carry out extracellular digestion, where enzymes break down the food particles and cells lining the gastrovascular cavity absorb the nutrients. Cnidarians have an incomplete digestive system with only one opening; the gastrovascular cavity serves as both a mouth and an anus.
Keeping this in consideration, how do cnidarians capture prey?
Cnidarians capture prey using stinging cells to inject venom. Then its tentacles pull the prey to its mouth. The food passes into a cavity where it is digested and exits through the mouth. How do cnidarians produce asexually?
How do cnidarians obtain energy?
Some obtain their energy from algae that that live in their bodies and a few are parasites. Other Cnidaria, including the corals, get their nutrients from symbiotic algae within their cells. In the Cnidaria sexual reproduction often involves a complex life cycle with both polyp and medusa stages.
