Q3. Why do starfish need to eat other organisms?
Answers
Answer:
Believe it or not, starfish (also known as a sea star) are carnivores, meaning they consume other creatures. Starfish consume creatures that move slowly because they also move extremely slowly. That is why they consume other organisms. Some of the starfish also eat other animals for example an fish if they are injured and unable to move away in time.
Explanation:
The majority of starfish are scavengers and carnivores. There are omnivorous species. Bivalves, gastropods, polychaetes, and barnacles are just a few examples of the slow-moving animals that these animals consume. Other starfish eat fish, planktons, and organic waste.
These prickly stars also consume algae, worms, prawns, clams, and coral. Even other smaller starfish will be eaten by them. It is challenging to feed them in aquariums because of their widely different diet. The best course of action is to consistently give larvae and other zooplankton.
Starfish needs to eat other organisms because they are carnivorous organisms and also are very slow movers.
Explanation:
1. Starfish feeds on various organisms such as sponges, oysters, corals, mussels, etc.
2. Starfish moves very slowly which means that their movement is very slow and therefore they feed on other organisms which moves slowly and remains attached to rocks.
3. Star fish also feeds on fish and other organisms and plants which are dead.
4. Starfish catches or traps other organisms with the help of suction cups which is present in their bottom. These structures helps the starfish to hold their prey.
5. After that, the stomach of starfish comes out of their mouth and begins digesting the parts of the prey organisms.
6. After digestion, the nutrients comes to pyloric ceca present at each arm through the pyloric ducts. Here in the pyloric ceca, the absorption of nutrition occurs.
