The influence of ocean temperature on marine biodiversity is significant because it affects metabolic rates and species distribution within marine ecosystems. Warmer water temperatures can increase the metabolic rates of marine organisms, leading to changes in growth, reproduction, and survival rates. For example, as the temperature rises, many species might find themselves in stress conditions, impacting their overall health and reproductive success.

Additionally, different marine species have specific temperature ranges within which they thrive. Changes in ocean temperature can shift these ranges, causing some species to migrate to cooler areas, while others may not be able to adapt quickly enough, leading to shifts in biodiversity. This redistribution of species can alter community interactions, food webs, and overall ecosystem dynamics. Thus, ocean temperature is a critical factor in determining which species can thrive and where they can be found, making it crucial to marine biodiversity.
