Sulfur and Phosphorus Cycles Overview

What is one primary distinction between the sulfur and phosphorus cycles?

• Sulfur cycle has an atmospheric component, phosphorus cycle does not.

• Phosphorus cycle has an atmospheric component, sulfur cycle does not.

• Both cycles have atmospheric components.

• Neither cycle has an atmospheric component.

How is sulfur released into the atmosphere?

• Through volcanic eruptions and burning fossil fuels.

• Through weathering of rocks.

• Through photosynthesis.

• Through decomposition of organic matter.

What is a key environmental impact of the sulfur cycle?

• Acid rain harming aquatic ecosystems and soil health.

• Eutrophication in water bodies.

• Depletion of soil nutrients.

• Increase in atmospheric carbon dioxide.

How does phosphorus primarily cycle through ecosystems?

• Through soil, water, and living organisms.

• Through the atmosphere.

• Through volcanic eruptions.

• Through industrial emissions.

What is a significant environmental impact of phosphorus runoff from agricultural fields?

• Eutrophication leading to algal blooms.

• Acid rain formation.

• Increase in atmospheric sulfur levels.

• Depletion of soil phosphorus.
