Sunflower Sea Stars eat a lot of different animals, but lets say clams. (Since Sunflower Sea Stars really do eat clams) If Sunflower Sea Stars kept dying there would be a lot of clams, and the clams would start eating a lot of what they eat and it would mess up everything.
a food web is a bunch of food chains combined because an animal crosses over to eat another in the other food chain. The following people assisted in producing these webpages.
Its sea star. At-risk reefs have low numbers of these top-level (apex) predators.
Some sea stars prey on sea urchins, mussels, and other shellfish that have no other natural predators. These are the large fish that excite divers. First off its not starfish. Tiny organisms can be swallowed whole. The object of this game is to encourage children to make food chains and see what happens if links in the chain are removed. The first importance is the act of sea star or starfish as a predator. 1. Barracuda, groupers, snappers, sharks, moray eels, and dolphins are at the top of the food chain.Their feast includes other fish, crustaceans, and even octopi. Bat Star (Patiria miniata) The Bat star is easily recognizable in that the arms are connected by a web. Beachy food chains 3 Game 2 - Making chains Maximum activity duration: 30 minutes Seaweed Winkle Lobster Human The labels on page three are arranged in food chains and coloured differently for five teams. Sea stars dont have bones, therfor they can't be classified as a fish.

Ochre Sea Stars are voracious predators on smaller animals, and among the very abundant animals on which they feed are mussels.
But to answer your question, They are predators. Sea-stars (Class Asteroidea). Fish are vertabrates-meaning they have bones. When the tide is high they will start moving around looking for food. They feed on bivalves (two shelled animals such as clams, musscles, oyssters) crabs, lobsters, and dead and decaying matter. Enzymes from the sea star’s stomach digest the prey. It has been estimated that an adult Ochre sea star will eat about 80 mussels in a year. If the sea star is removed from the ecosystem, the mussel population explodes uncontrollably, driving out most other species. a food web is a bunch of food chains combined because an animal crosses over to eat another in the other food chain. This is about the food chain. Without starfish the amount of their prey will go higher and make the ecosystem unbalance. Part 1. Light-sensitive eyespots on the tips of the arms help the sea star find food. (Since Sunflower Sea Stars really do eat clams) If Sunflower Sea Stars kept dying there would be a lot of clams, and the clams would start eating a lot of what they eat and it would mess up everything. Besides having an act as a predator in the ocean, starfish also having an act as a prey. 400-418 7 figs pl. Favorites on the menu include mollusks such as clams, oysters, and snails. Sunflower Sea Stars eat a lot of different animals, but lets say clams. Act as a prey. Although their motion across the sea bottom is fairly slow, they do move about when searching for prey. pp. A sea star envelops a mussel with its arms and, by applying many tube feet to each valve, is able to pull the shells slightly apart, no easy feat. Here is a example of a food chain. Adults are usually between 8-12 inches but larger specimens can be found. The digested material enters the sea star’s stomach. 2. The sea star eats by attaching to prey and extending its stomach out through its mouth. Seastars/starfish of the Sydney region project, acknowledgements. This is not only applied for starfish but also applied for another types of ocean predators. Ms Adrienne Gatt took most of the images of preserved specimens.
