Phosphorus Cycle

Front

What is the phosphorus cycle?

Back

The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere, essential for life as it is a key component of DNA, RNA, and ATP.

Front

Which substances contain phosphorus?

Back

Phosphorus is found in DNA, RNA, cell membranes, and rocks, but not in pure water.

Front

What is the significance of phosphorus in agriculture?

Back

Phosphorus plays a crucial role in agricultural practices by improving yield, which helps maintain balance in the ecosystem's energy flow.

Front

What is phosphorus runoff?

Back

Phosphorus runoff is the movement of phosphorus from land to water bodies, causing eutrophication and other negative impacts on water quality.

Front

What is sedimentation?

Back

Sedimentation is the process by which material is deposited or settles in a location until forming sedimentary rocks.

Front

How does weathering release phosphorus into the environment?

Back

Weathering breaks down rocks containing phosphorus minerals, releasing phosphorus into the soil.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

Why is phosphorus important for plants?

Back

Phosphorus is essential for plant growth as it is a key component of nucleic acids and ATP, which are vital for energy transfer and genetic information.

Front

What are the main sources of phosphorus in the environment?

Back

Main sources of phosphorus include fertilizers, animal waste, and natural mineral deposits.

Front

What role do decomposers play in the phosphorus cycle?

Back

Decomposers break down organic matter, releasing phosphorus back into the soil and making it available for plant uptake.
