Answer 2

The correct answer would be Algae contributes to the phosphorus cycle.

Algae refer to the diverse group of non-flowering photosynthetic eukaryotic organisms which belong to the kingdom Protista.

They serve numerous commercial or industrial uses such as used as soil fertilizers, used in wastewater treatment, production of industrial products such as fuel, food, medicines, animal feed et cetera.

However, they are not used in the phosphorus cycle. Instead, soil bacteria help in breaking down organic compounds into the inorganic form of phosphorus in the soil.
