Sentences with phrase «phosphorus cycle»
The phrase "phosphorus cycle" refers to the natural process through which phosphorus, a vital nutrient for living organisms, circulates and is recycled in the environment. It involves the movement of phosphorus from rock to soil, then to plants, animals, and eventually back to the soil and water through processes like decomposition and excretion. This cycle ensures the availability of phosphorus for various life forms and is essential for maintaining healthy ecosystems. Full definition
But just how significant is lightning to the global phosphorus cycle?

Could improving our management of the nitrogen and phosphorus cycles also contribute to climate change mitigation or adaptation?
Thus, managing the nitrogen and phosphorus cycles sustainably becomes a classic optimization problem, one that emphasizes waste reduction while enhancing food quality, quantity, and accessibility.
How do carbon, nitrogen and phosphorus cycles regulate climate system feedbacks, and how sensitive are these feedbacks to model structural uncertainty?
Admittedly, the threats and opportunities of altered nitrogen and phosphorus cycles pose some unique challenges for human society.
We intervene in the phosphorus cycle by mining rock phosphate and adding it to soil as fertilizer.
All other elements that are necessary for life have their own cycles in nature such as, for example, the phosphorus cycle and the sulfur cycle.
The findings suggest that human - caused acceleration of global nitrogen and phosphorus cycles have boosted nitrogen removal processes in small to medium - size lakes.
They identified 10 environmental limits we might not want to transgress in the Anthropocene: aerosol pollution; biodiversity loss; chemical pollution; climate change; freshwater use; changes in land use (forests to fields, for example); nitrogen and phosphorus cycles; ocean acidity; and the ozone hole.
One possibility is that the spread of invasive quagga and zebra mussels in the lake has promoted the dominance of microcystin - producing cyanobacteria and has altered the lake's phosphorus cycle.
«Our research is an attempt to place the spread of animal life in the context of wider biogeochemical cycles, and we conclude that animal activity had a decreasing impact on the global oxygen reservoir and introduced a stabilizing effect on the connection between the oxygen and phosphorus cycles,» says lead author Dr. Richard Boyle from the Nordic Center for Earth Evolution (NordCEE) at the University of Southern Denmark.
When these worms began to mix up the ocean floor's sediments (a process known as bioturbation), their activity came to significantly influence the ocean's phosphorus cycle and as a result, the amount of oxygen in Earth's atmosphere.
Perhaps the most significant advancement, however, is the introduction of the phosphorus cycle to the code.
We are altering the carbon, nitrogen, water and phosphorus cycles.
At the same time, a more efficient, less polluting relationship with the global nitrogen and phosphorus cycles would mitigate a host of other environmental challenges, increase food security, improve human welfare, lessen some national security concerns, and probably save money.
Thus, even without the prospect of climate change, we need to shift the ways we interact with and manage the nitrogen and phosphorus cycles.
Feeding people is a good thing, but our ability to transform the nitrogen and phosphorus cycles has had startling and unsustainable consequences.
Of course, there is a major upside to our domination of the global nitrogen and phosphorus cycles.
Global freshwater usage, changes in land use, ocean acidification and interference in the phosphorus cycle are already reaching their limits.
