Phosphorus Cycle

Front

What role do decomposers play in the phosphorus cycle?

Back

Decomposers return phosphorous into the soil by breaking down organic matter.

Front

What processes are utilized in the phosphorus cycle?

Back

The phosphorus cycle utilizes the processes of erosion and weathering.

Front

How does phosphorus enter waterways?

Back

Phosphorus enters waterways primarily through runoff.

Front

Which of the following is NOT a part of the phosphorus cycle?

Back

Atmospheric phosphate is NOT a part of the phosphorus cycle.

Front

What is eutrophication?

Back

Eutrophication is the process where excess phosphorus in waterways leads to overgrowth of algae, depleting oxygen and harming aquatic life.

Front

What is the main source of phosphorus for plants?

Back

Phosphorus is mainly absorbed from the soil by plants.

Front

What is the significance of sedimentary rocks in the phosphorus cycle?

Back

Phosphate is incorporated into sedimentary rocks, which can release phosphorus back into the soil over time.

Front

How do human activities impact the phosphorus cycle?

Back

Human activities, such as agriculture and wastewater discharge, can increase phosphorus levels in waterways, leading to eutrophication.

Front

What is the role of weathering in the phosphorus cycle?

Back

Weathering breaks down rocks, releasing phosphates into the soil and making them available for plant uptake.

Front

What are phosphates?

Back

Phosphates are chemical compounds containing phosphorus, essential for plant growth.
