What is the benefit of physical/harvesting aquatic plants?

• A. Removal of nutrients from the pond
• B. Increases nutrient load
• C. Decreases water clarity
• D. Speeds up weed growth

Answer: (A)

Plants take up nutrients from the water, so when you physically harvest and remove them, you’re taking those nutrients out of the pond. That lowers the pool of nutrients (like nitrogen and phosphorus) available in the water, which reduces the potential for new plant and algal growth and helps improve overall water quality. If the harvested material were left to decay, those nutrients would be released back into the water, undermining the benefit. The other options describe outcomes that would not result from harvesting: adding nutrients, reducing clarity, or speeding up weed growth.
