What is a consequence of nutrient cycling imbalance?

A consequence of nutrient cycling imbalance is indeed reduced agricultural productivity. Nutrient cycling refers to the natural process by which nutrients are recycled in the ecosystem, involving their uptake by plants, consumption by animals, decomposition, and eventual return to the soil.

When there is an imbalance in this cycle, it often results in the depletion of essential nutrients from the soil, such as nitrogen, phosphorus, and potassium, which are crucial for plant growth. A lack of these nutrients can lead to poor crop yields and reduced agricultural productivity, making it difficult for farmers to sustain their operations and feed populations.

In contrast, the other options indicate positive outcomes that are generally associated with a balanced nutrient cycling process. Increased soil fertility, improved biodiversity, and enhanced water quality are typically the result of effective nutrient cycling. When nutrients are adequately cycled, they support healthy plant growth, diverse ecosystems, and processes that improve water quality.
