Question
Scientists discover that run off from some plant fertilizers can produce algal blooms that
negatively affect ocean systems. Which of the following options provides evidence of
how algal blooms harm ocean ecosystems? (1 point)
Rainfall and irrigation can cause excess water to enter the soil, resulting in excess fertilizer runoff that ends up in the ocean
Authorities warn the public not to let their dogs swim in water bodies with algal bloom
since they could get sick from algae exposure.
Large algal blooms rapidly decompose, contributing to increased carbon dioxide and low oxygen water that can reduce fish habitats.
Excessive nutrients from fertilizer runoff increase the amount of plant and algae growth and water bodies.

Large algal blooms rapidly decompose, contributing to increased carbon dioxide and low oxygen water that can reduce fish habitats.
Explanation: When blooms die and decompose, microbes consume oxygen, creating hypoxic "dead zones" that kill or displace marine life and degrade ecosystems.
