Phosphorus is required for organisms to synthesize DNA and phospholipids. In an ecosystem, phosphorus is transferred into the soil by the weathering of rocks. Phosphorus is absorbed by plants, which are consumed by herbivores. Carnivores obtain phosphorus through the consumption of herbivores. Which is a process that transfers phosphorus between an abiotic system and a biotic system.
