In a Penn State release, Cheng detailed the findings: "It's like when we do fitness training and a trainer says to tighten your core to be more agile. 4. /ExtGState << So, naturally keeping a check on these small organisms populations is a must to keep a balance in the ecosystem. It is only natural for this to happen because when various species interact with one another, some form relationships with other organisms that specifically contribute more to the environment. (Lets Know). endobj Starfish acts as Keystone Species as they due to their presence in the ecosystem are known to keep tidal pools of the respective marine environment in an ecological balance. They do also help in cleaning the ecosystem by consuming the scattered pieces of rubbish or remains of other small organic seaweeds and organisms that are at the ocean floor and nearby rocks. degradation and fragmentation making this species particularly vulnerable.
