clownfish that live in the anemone’s tentacles to gain protection from
predators.

Nutrients include phosphorus (P) and nitrogen (N). When there are lots of nutrients, this may cause algae and phytoplankton to grow.

It is very difficult for corals to grow in acidic conditions. ]]> 2021-05-12 16:22:14 UTC https://padlet.com/shelbybezner9/12rafuffmr2o14f1/wish/1518179749 shelbybezner9 https://padlet.com/shelbybezner9/12rafuffmr2o14f1/wish/1537296975 Humans are one of the biggest threats to the coral reef ecosystem, and are the reason why the population of coral reefs are declining. Several laws have already been put in place to protect the coral reefs, including Magnuson-Stevens Fishery Conservation and Management Act which regulates fishing, as overfishing is a severe problem, and protects essential fish habitats. Pollution also greatly affects the coral reef ecosystem, as it throws off the natural balance of the entire ecosystem and damages the environment. Global warming is probably the biggest threat to coral reefs, however. This warming causes corals to lose the microscopic algae that produce food that corals need, placing stress on the corals. Without this algae coral also lose their coloration—a condition known as coral bleaching— because the loss of algae reveals the white color of the calcium carbonate structure underlying the polyps. Severe or prolonged bleaching can kill coral colonies or leave them more vulnerable to other threats such as infectious disease.]]> 2021-05-18 19:42:35 UTC https://padlet.com/shelbybezner9/12rafuffmr2o14f1/wish/1537296975 shelbybezner9 https://padlet.com/shelbybezner9/12rafuffmr2o14f1/wish/1537313573 A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.]]> 2021-05-18 19:47:23 UTC https://padlet.com/shelbybezner9/12rafuffmr2o14f1/wish/1537313573
