Answers:
The ways to speed up photosynthesis is to <u>increase the amount of light </u>because with minimal light it slows photosynthesis down. Photosynthesis is also <u>dependent on temperature</u> and when the enzymes reach the perfect temperature which is around <u>50-68 degrees fahrenheit. An increase in carbon dioxide </u>will also speed up photosynthesis (this is more possible in a greenhouse). Carbon dioxide is used to make the sugar in order to create the reaction for photosynthesis to happen.
Answer:
Ocean acidification: Ocean acidification refers to the decrease in the pH of ocean water.
The pH of ocean water decreases due to the increased in the carbondioxode emissions in the atmosphere because of the burning of fuels. This carbondioxode is dissolved in the ocean water and forms carbonic acid. This carbonic acid is responsible for increasing the pH of ocean water. In one and half century, there is 30% increase occurs in the acidity of ocean water.
