Use the following information to answer the next question
Coral reefs all over the world are starting to die due various factors affecting the microscopic zooxanthellae that live inside of coral. The zooxanthellae and coral have a symbiotic relationship. The coral provides the zooxanthellae with carbon dioxide, nutrients and protection. The zooxanthellae provide the coral with sugars as they perform photosynthesis.
Answer each of the following and label your answers (ex: 1.____, 2.___)
1. An increase in ATP and NADPH and a decrease in Sugars means which of the following is not working? Explain why!
a. Photosystem I
b. Photosystem II
c. Calvin Cycle
2. Based on the information above, which of the following is the most likely cause of coral death in this ecosystem?
