Question

Which of the following statements as the oceans get warmer?

a) More reefs are developing as the oceans get warmer
b) Large areas of existing reefs have been dying off due to bleaching and various coral diseases
c) As time passes, seamounts emerge from the sea, and atolls become fringing reefs
d) The coral making reefs is a species of algae that secretes a siliceous shell

Answer 1

The correct statement is that large areas of existing reefs have been dying off due to bleaching and various coral diseases as the oceans get warmer. The correct option is b) Large areas of existing reefs have been dying off due to bleaching and various coral diseases

Step-by-step explanation:

The correct statement out of the given options is b) Large areas of existing reefs have been dying off due to bleaching and various coral diseases.

As global warming raises ocean temperatures, coral reefs are suffering. The excessive warmth causes the reefs to lose their symbiotic, food-producing algae, resulting in a phenomenon known as bleaching. When bleaching occurs, the reefs lose much of their characteristic color as the algae and the coral animals die if loss of the symbiotic zooxanthellae is prolonged.

This process has led to the death of large areas of existing reefs, impacting the biodiversity of marine life and posing a serious threat to coastal economies.The correct option is b) Large areas of existing reefs have been dying off due to bleaching and various coral diseases
