Question

how can rising water temperatures affect coral reef ecosystems? choose two correct answers.
coral species do not survive.
coral reefs expand.
sea life overwhelms the reef.
coral bleaching occurs.
fish species are at risk.
this question requires at least 2 answers.

Explanation:

• Coral species do not survive: Rising water temperatures can be too extreme for coral species to handle, leading to their death.
• Coral bleaching occurs: When water temperatures rise, corals expel the symbiotic algae (zooxanthellae) living in their tissues, causing coral bleaching.
• Fish species are at risk: Corals provide habitat and food for fish. If corals are affected by rising temperatures (e.g., die or bleach), the fish that depend on them are also at risk.

Answer:

Coral species do not survive, Coral bleaching occurs, Fish species are at risk.
