Step 1
The main abiotic reservoir for phosphorus is in rock and soil minerals, not water. B) Plants release dissolved phosphorus ions in the soil: This is not true. Plants actually absorb phosphorus from the soil, they do not release it. Show more…

Which of the following statements about the phosphorus cycle is false? Plants release dissolved phosphate ions into the soil. The main abiotic reservoir for phosphorus is in the air. Guano, the excrement of birds and bats, can be used by farmers to add phosphorus to the soil. Phosphates that drain from soils into the sea becomes part of new rock and will cycle back into living organisms.

Which of the following statements are true about the phosphorus cycle? Select all that apply: Phosphorus is a key component of DNA and RNA Weathering of rocks decreases phosphorus availability over long timescales Organisms obtain phosphorus primarily through direct capture from atmospheric gases Most phosphorus ends up in the ocean after being used in terrestrial ecosystems Humans synthesize phosphorus fertilizer using the Haber-Bosch processing
