Question

One of the most common plants in Atlantic salt marshes is cordgrass. periwinkle snails cling to the top of tall cord grass is during high tide. The tall cord grass is provide protection from the snails predators such as blue crab. well the snails do not be directly on cordgrass the snails can damage the cord grass when they grays and algae and fungi that grow on the grasses. if the snail populations grow too large they can decrease cord grass growth.

Answer 1

One of the most common plants in Atlantic salt marshes is Cordgrass. periwinkle snails cling to the top of tall cord grass is during high tide. We can say that the symbiotic relationship exhibited between the periwinkle snails and the cordgrass is parasitic in nature.

A parasitic relationship is a relationship between two organisms in which one species benefit from the other organism, and the other organism is being harmed.

However;

• the blue crab → hawk (predator)
• Algae → wildflowers
• periwinkle snail → Bison which feds on wildflowers.

From the given question, the periwinkles snails survive the storm during high tide waves because of the protection offered by the cordgrass tall plant. But over time, the cordgrass growth decreases as a result of the large population of the snail. Thus, this relationship between the cordgrass and the periwinkles snails is parasitic in nature.

Therefore, we can conclude that the symbiotic relationship between the periwinkle snails and the blue crab is parasitic in nature.
