In the popular usage, they are already dead or fossilized and therefore do not have any excretory capacity, any more than say, dinosaurs fossils. When alive, that is someting else. Coral are marine life ( one is not sure if they are fauna or flora- perhaps something in between. in the popular sense-as decorative items- they were once the national jewel of Italy, they are already extinct- that is dead- and do not have any excretory or intake capacity. It should be noted that Seahorses externally fossilize also and many are small, the size of a quarter. Either they die young or are a smaller variant of the species. the largest Sea Horses can top about l4 inches. Seahorses are fish, bizarre as they appear.
Coral Reefs
Coral poops by expelling waste out through the pharnyx.
Many have photosynthesizing algae within their tissue that produce oxygen. Dead coral also produces the foundation on which future generations of coral will live.
no
By breaking off and making new corals.
we produce poo
for starters there is no such thing as deep sea coral coral lis only in shallow water so the answer to the question you asked is no.
Yes, all living organisms produce waste, including the Bobcat.
The way coral reefs are being endangered are by us. We keep on throwing waste on the beaches. The water washes up on shore. And the waste floats down to the coral reefs. And the fishes and species that live there are either eating it or living in it. If they eat it the chemicals in the waste can kill them! if they are living in them then the saltwater in the coral reefs since the water is so warm, it release the chemicals in the water and the water gets into the species gills and kills them. It is up to us to stop throwing or leaving waste on the beaches so the coral reefs aren't in dangered anymore. So that is how the caorl reefs are endangered.
It would be most like jellyfish skin but coral also produce the rocky shell that is left over even after they die.
Animals eat food and absorb the vitamins, nutrients and energy and produce waste from the materials the body does not need. The bodies of dead animals also decay and produce waste.
put it in an oven
