Question

which of the following products cause disruptions to the phosphorus cycle?
select 2 correct answers.
a pesticides
b fertilizer
c cleaning products
d fossil fuels

Explanation:

• Fertilizer: It contains phosphorus. Excessive use leads to runoff, increasing phosphorus in water bodies, causing algal blooms and disrupting the phosphorus cycle.
• Cleaning products: Some (like certain detergents) have phosphorus. When they enter water systems (e.g., through wastewater), they add extra phosphorus, disturbing the natural balance of the phosphorus cycle.
• Pesticides mainly affect pest populations and ecosystems in terms of killing pests, not directly the phosphorus cycle. Fossil fuels are more related to carbon - based emissions (e.g., carbon dioxide release) rather than phosphorus cycle disruption.

Answer:

B. fertilizer, C. cleaning products
