o the algae thrive providing benefits for coral
o the algae become harmful to coral and are expelled
o the algae are susceptible to infection
o the algae become palr

Answer 1

When the temperature in the ocean becomes too hot, the algae that live in symbiosis with coral, primarily zooxanthellae, often become harmful to the coral and are expelled. This process is known as coral bleaching. High temperatures can stress the coral, leading to the breakdown of the relationship between the coral and the algae. As a result, the coral loses its primary source of energy, which can lead to coral death if the stressful conditions persist. Thus, the correct answer is:

**o the algae become harmful to coral and are expelled.**
