The average global ocean temperature in 1912 was 15.8°C, and in 2011 this temperature was 16.5°C. Algae grow best in a range of 16°C to 27°C. What is the predicted impact of the change in average ocean temperature on algae?

an increase in algae

elimination of predators on algae

narrowing of the ecological niche for algae

The predicted impact of the change in average ocean temperature on algae would be a narrowing of the ecological niche for algae. While the increase in temperature falls within the optimal range for algae growth, it is still only a small increase and may not necessarily cause a significant increase in algae populations. Additionally, other factors such as nutrient availability and competition with other organisms also influence the growth of algae. Therefore, it is more likely that the change in temperature will lead to a narrowing of the temperature range within which algae can thrive, rather than a significant increase or elimination of predators.
