no
they aren't
Yes. All animals balance the ecosystem.
If the ochre sea star were removed from the ecosystem, shellfish populations could increase significantly. Ochre sea stars are predators of shellfish, and without them, shellfish could thrive unchecked, leading to potential overgrazing of algae and other organisms in the ecosystem. This could disrupt the balance of the ecosystem and impact other species dependent on these resources.
it is important because they prevent the soil erosion along the sea coast.
A sea star is called a sea star simply because of where it lives (the sea) and what it looks like (a star), simple!
a sea is an ecosystem because it helps and provides for communities and populations. there is another world of animals that live in the sea. the sea is like above the ground but it is under water (:
Sea stars would live in a clear water rock pool. They would hide under rock pools. I found some in Deewhy beach. They where in the middle section.
When sea urchins are not present in the ecosystem kelp forests thrive.
no, a sea star is a vertebrate!
the sunflower sea star
Of course it is. They are part of an important ecosystem and the foodchain. Polar bears are majestic animals.
Some common consumers in the intertidal zone include periwinkle snails, sea anemones, crabs, mussels, barnacles, limpets, sea urchins, and sea stars. These animals play important roles in the ecosystem by feeding on various organisms and helping to regulate population levels.
