Question

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

Answer 1

The predicted impact of the change in the average ocean temperature from 15.8°C to 16.5°C on algae is an increase in algae growth. This is because the optimal temperature for algae growth falls within the 16°C to 27°C range, and the increase in ocean temperature now falls within this range. Therefore, the increase in temperature may lead to an increase in the proliferation of algae species in the oceans. However, it is important to note that other environmental factors such as nutrient availability and light availability can also impact algae growth.
