Question

question 1 - 11
a student collects data from two wetland ecosystems. wetland a shows high levels of nitrate and phosphate, while wetland b shows very low levels of both.
based on this data, which of the following is the most reasonable conclusion about how biogeochemical cycles support a sustainable ecosystem?
○ wetland b will have limited plant productivity because it has low levels of nutrients.
○ wetland a will not change as it has balanced levels of nutrients in the water.
○ wetland b will have greater biodiversity because it has fewer nutrients in circulation.
○ wetland a is likely to experience eutrophication because it has low nutrient levels.

Explanation:

Nutrients like nitrate and phosphate are crucial for plant growth. Wetland B has low nutrient levels, which will limit plant productivity. High - nutrient levels in Wetland A can lead to eutrophication, not low levels. Balanced nutrients don't mean no change in an ecosystem, and fewer nutrients usually don't lead to greater biodiversity as plants need nutrients to thrive.

Answer:

Wetland B will have limited plant productivity because it has low levels of nutrients.
