I'm just guessing, but somebody goes hungry.....go figure.....
As consumers (chemoheterotrophs), animals cannot produce their own food. Any lost link in the food chain prevents the organisms above that point from surviving, at least in their current position on the chain.
it could affect a lot more organisms living in the ocean
A broken link on a manure spreader chain can be fixed by using a linkage connector. Linkage connectors of this type can be found at many farm implement dealers.
a link broken
First link on food chain
The food chain will not be successful since the organism which depends on the removed food will start looking for something else to depend on or will starve to dead e.g if the grasshopper depends on grass for it survival and the grass is distorted in the food chain the grasshopper will surely die
a link in the food chain is probable broken. ( a species became extinct)

because it needs a lot of energy to get the food chain to cycle.
