51. Coral reefs are now under massive bleaching which is attributed to the main reason as described in "Option B" i.e rise in temperature of sea level.
The of overall percentage of presence of coral reefs have become almost to its half and this is the result of a massive bleaching. So these species are also considered as entities under the endangered species.
52. Among all the forms of flightless birds found in Antarctica, the majority is ruled by penguins "ie Option C" or the third option, that comprise most of the regions around the Southern Hemisphere of this continent.
Answer:
Rise in temperature of the sea.
Explanation:
When algae is expelled from the tissues of the coral, causing it to turn white and whitening of the coral is known as coral bleaching. Without algae the coral losses it source of food and therefore it is more susceptible to disease. When temperature is high, high solar irradiance contributes to bleaching.
