Final answer:

Human activities like agricultural and urban runoff with excess phosphorus cause algal blooms in water bodies.


Explanation:

Phosphorus pollution leading to algal blooms in water bodies is primarily caused by human activities such as agricultural and urban runoff containing excess phosphorus from fertilizers and detergents. The introduction of phosphorus-containing detergents in the 1950s significantly contributed to the increase in phosphorus available to algae, leading to cultural eutrophication and algal blooms.
