What is the role of geological uplifting in
the phosphorous cycle?

a. it releases phosphorous stores in rocks and minerals so it can be used by living things

b. it converts atmospheric carbon into phosphate that fish require

c. it converts phosphorus into a form that living things can more easily use

d. it pulls excess phosphorous out of the cycle, preventing algal blooms

The answer is (A)

Because geological uplift carries naturally occurring minerals to the surface, and with the help of weathering (long exposure to air), releases phosphate ions. The phosphates are then transferred from plants to herbivore animals. These herbivores are then eaten by carnivores. The phosphates that are absorbed by the animals are returned to the soil through excretion and from decomposition of plants and dead material by microbes.
