Front

What nutrient is not cycled through the atmosphere and stays only on ground level?

Back

Phosphorus

Front

What process brings phosphorus into our waterways?

Back

Runoff

Front

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

Back

Atmospheric phosphate

Front

What is the major sink for phosphorus?

Back

Sedimentary rock

Front

What human activities significantly impact the phosphorus cycle?

Back

The use of fertilizer, artificial eutrophication, and the distribution of food products.

Front

Define the phosphorus cycle.

Back

The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere, primarily through soil, water, and living organisms.

Front

Why is phosphorus important for living organisms?

Back

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

Front

What role do plants play in the phosphorus cycle?

Back

Plants absorb phosphorus from the soil, which is then used for growth and development.

Front

How does phosphorus enter the soil?

Back

Phosphorus enters the soil through weathering of rocks and the decomposition of organic matter.

Front

What is artificial eutrophication?

Back

Artificial eutrophication is the process where water bodies receive excess nutrients, often from fertilizers, leading to algal blooms and oxygen depletion.
