Question

Coral reefs can not survive in water having
temperature?
O Less than 22 degree centigrade
O Less than 24 degree centigrade
O Greater than 20 degree centigrade
O At 26 degree centigrade​

Answer 1

Answer:

Because of strict environmental restrictions, coral reefs generally are confined to tropical and semi-tropical waters. Reef-building corals cannot tolerate water temperatures below 64° Fahrenheit (18° Celsius).

Explanation:

Answer 2

Coral reefs can not survive in water having a temperature less than 22° centigrade.

• Corals usually grow well in warm water.
• Coldwater conditions are not favorable to their growth.
• Most corals feed on phytoplankton and dinoflagellates that live among them for nutrition.
• These organisms can survive only in the presence of sunlight.
• Thus the survival of corals indirectly depends on the presence of sunlight. This is why they cannot survive in colder regions.
