pollution, boat traffic, higher temperatures (caused by climate change - cause coral bleaching) and aggressive fishing.
Coral reef bleaching is the result of the die-off of certain coral. Coral reef bleaching is the whitening of diverse invertebrate taxa. Coral reef bleaching is caused by various anthropogenic and natural variations in the reef environment including sea temperature, solar irradiance, sedimentation, xenobiotics, subaerial exposure, inorganic nutrients, freshwater dilution, and epizootics.
it kills bacteria
This is a bit misleading because the word "coral" is misspelled "choral." Coral bleaching kills living coral organisms and is very prevalent in parts of the Carribbean. The coral appears pale white (or "bleached") instead of its normal gray-green-brown hues. Coral heads are actually made up of thousands of tiny, living organisms. Coral bleaching kills the coral and produces the white, bleached appearance. The coral can recover; however, it takes many, many years for coral to grow to a sizeable mass. Coral bleaching often kills the entire coral colony. Global warming is thought to contribute to coral bleaching: the problem in the Carribbean has worsened with just a one- or two-degree increase in water temperature.
It dies, coral bleaching.
Yes.
I am not aware that any scientist considers coral bleaching to be advantageous; bleaching indicates the death of symbiotic algae within the coral, leading to the death of the coral itself, leading to a greatly reduced oceanic biodiversity, which is a bad thing.
Changes in normal temperature (particularly short-term changes at the sea surface), incoming solar radiation, and the chemistry and composition of sea water (including pollution) affect coral to differing extents, and all can cause bleaching. Bleaching is largely reversible unless it happens for an extended period of time, so if the question refers to permanent bleaching, then all of these factors can cause it, but temperature would be by far the largest influence. As an interesting side note, coral in the Red Sea lives at some of the highest temperatures of any coral anywhere else in the world, as the sea is much warmer than any open ocean.
um no algae is biotic because it is a plant um no algae is biotic because it is a plant
The main culprit of coral bleaching is elevated sea temperatures caused by climate change. When corals are stressed by high temperatures, they expel the algae living in their tissues, causing the coral to turn white and potentially die if the stress is prolonged.
Elevated levels of carbon dioxide in the atmosphere are causing ocean temperatures to rise and oceans to become more acidic. This leads to coral bleaching by putting stress on coral reefs, which rely on a delicate balance of temperature and acidity to survive. Additionally, coral bleaching can also be triggered by pollution, overfishing, and other human activities that disrupt the natural carbon cycle.
no the can't poison sticks to them and cannot come off
