Final answer:

Ocean acidification and algal blooms are caused by changes in biogeochemical cycles due to human activities, impacting marine ecosystems.


Explanation:

Ocean acidification is caused by changes in the biogeochemical cycles of the planet, particularly due to the excessive uptake of carbon dioxide from the atmosphere, leading to a decrease in pH of marine environments. This alteration affects marine life, including coccoliths, nitrogen fixation, and higher trophic levels. Algal blooms are also a consequence of biogeochemical changes, such as eutrophication from high levels of nutrients like nitrogen and phosphorus, resulting in disruptive overgrowths of algae that deplete oxygen levels and harm aquatic ecosystems.
