the phosphorus cycle
plant tissues
animal tissues
and feces
decomposition
by fungi and
bacteria
assimilation
by plant cells
weathering
of rock
phosphates
in soil
loss in
drainage

• incorporation into sedimentary rock
• geologic uplift into terrestrial

environments
which abiotic factor is primarily responsible for providing phosphates to plan
rainwater
rock
wastewater
feces

Explanation:

1. First, recall the definition of abiotic factors (non - living components of an ecosystem) and biotic factors (living or once - living components). Feces (from animals) and wastewater (related to human or animal activities) are biotic or related to biotic processes, so they can be eliminated.
2. Then, look at the phosphorus cycle model. The step "weathering of rock" leads to "phosphates in soil", and rock is an abiotic factor. Rainwater is involved in weathering but the primary source of phosphates for plants (via weathering to release phosphates) comes from rock.

Answer:

rock (the option with "rock" as the text, assuming the option format is like the one shown, e.g., if the option is "rock" with a radio button, then the answer is the option corresponding to rock)
