Question

phosphorus cycle
uplifting of rock
phosphates in rock
plants
animals
detritus
decomposition
detritivores in soil
precipitated (solid) phosphates
rock

Explanation:

To analyze the phosphorus cycle diagram, we identify the missing components based on the phosphorus cycle process:

1. Weathering (Top - left box, connected to “Rock” and “Precipitated (solid) phosphates”):

Phosphorus - rich rocks undergo weathering (physical/chemical breakdown) to release phosphates into soil/water.

2. Runoff (Middle - left box, connected to “Precipitated (solid) phosphates” and “Phosphates in rock”):

Water (e.g., rain, rivers) carries dissolved or solid phosphates in a process called runoff, moving them to aquatic ecosystems or depositing them.

3. Absorption by Plants (Middle - bottom box, connected to “Phosphates in rock” and “Plants”):

Plants take up inorganic phosphates from soil (via roots) or water (aquatic plants) through absorption (assimilation) to use in organic molecules (e.g., DNA, ATP).

4. Consumption by Animals (Bottom - right box, connected to “Plants” and “Animals”):

Animals obtain phosphorus by consuming plants (or other animals) that have assimilated phosphorus, incorporating it into their tissues.

5. Excretion/Decomposition (Bottom - left box, connected to “Animals”, “Detritus”, and “Decomposition”):

When animals excrete waste or organisms die, decomposers (bacteria/fungi) break down organic matter, releasing phosphates back into the soil (or water) as inorganic phosphates.

If the question was to label the boxes (common for phosphorus cycle diagrams), the typical labels (from top - left, middle - left, middle - bottom, bottom - right, bottom - left) would be:

1. Weathering
2. Runoff
3. Absorption (by plants)
4. Consumption (by animals)
5. Decomposition (and mineralization)

(Note: The exact labels depend on the diagram’s arrow directions, but this follows the standard phosphorus cycle: rock weathering → phosphate release → plant uptake → animal consumption → decomposition → phosphate return to environment/rock cycle.)
