Climate change has caused the ocean’s waters to become slightly acidic. This means the chemical composition of the water has changed, which “suffocated the corals in the Great Barrier Reefs in Australia. Which of the following would best fit the outcome of this scenario?
The biodiversity of the Great Barrier Reef has increased now because the corals have died.
The fish biodiversity increases because they also suffocated from the water and died
The change in the water’s acidity negatively changed the entire ecosystem’s biodiversity.
The change in the water’s acidity did not affect the biodiversity of the Great Barrier Reef.
