what is the sand dollars kingdom
Sand dollars occupy a specific ecological niche in sandy, shallow marine environments, primarily along coastal regions. They play a role in the benthic ecosystem by feeding on small organic particles and microorganisms found in the sediment, thus helping to recycle nutrients. Additionally, sand dollars serve as prey for various predators, contributing to the food web. Their unique adaptations, such as a flattened body and specialized spines, allow them to thrive in their sandy habitats.
