Climate change can have a large impact on coral reefs. How does climate change impact coral?

Climate change decreases the pH of seawater, which makes it harder for coral to grow.

Climate change lowers the temperature of seawater, which interferes with coral's symbiotic relationship with algae.

Climate change keeps pH levels of seawater stable, which allows coral to grow rapidly.

Climate change raises the temperature of seawater, which interferes with coral's symbiotic relationship with algae.

Respuesta :

The answer is the very last one

Answer: Option (4)

Explanation: Corals are directly related to the algae as corals provides the necessary conditions and nutrients for their growth and photosynthesis process.

A rise or fall in the temperature will affect both corals as well as algae, thereby causing disturbances in their mutual relationship. Due to the increasing temperature, ocean undergoes acidification, as a result of which the pH level will decrease in the sea water and the marine species also will be affected.

Thus, the most appropriate answer is option (4).
