The phosphorus cycle Kai

What is the phosphorus cycle?

The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere.

Why is phosphorus important for living organisms?

Phosphorus is essential for the formation of DNA, RNA, and ATP, which are critical for energy transfer and genetic information.

How does phosphorus enter the soil?

Phosphorus enters the soil through weathering of rocks and minerals that contain phosphate.

What role do plants play in the phosphorus cycle?

Plants absorb phosphorus from the soil, using it to grow and produce energy.

How do animals contribute to the phosphorus cycle?

Animals obtain phosphorus by consuming plants or other animals and return it to the soil through waste or decomposition.

What is eutrophication?

Eutrophication is the nutrient enrichment of water bodies, often caused by runoff containing excess phosphorus, leading to excessive algae growth.

What human activities impact the phosphorus cycle?

Human activities such as agriculture (fertilizer use) and wastewater discharge contribute to phosphorus runoff into water bodies.

What are phosphate fertilizers?

Phosphate fertilizers are chemical products used in agriculture to replenish phosphorus levels in the soil.

How does the phosphorus cycle differ from the nitrogen cycle?

The phosphorus cycle does not have a significant gaseous phase, while the nitrogen cycle includes atmospheric nitrogen.

What happens to phosphorus when it accumulates in aquatic systems?

Accumulated phosphorus can lead to algal blooms, which deplete oxygen in the water and harm aquatic life.
