Answer:
A. Overtillage can increase the rate of humus decomposition
Explanation:
We refer to humus as any material of an organic nature that undergoes soil degradation. Humus is very important for agriculture because it has high nutrient levels that it provides to all crops. This causes more crop productivity, increases the producer's profit and increases the number of food available to the population.
Humus is a difficult to decompose material, but under favorable conditions it can decompose quite easily. Due to the presence of large amount of burnt organic matter in the soil, it is sometimes difficult to increase the humus content, so the exhaustion of this organic matter is caused by over tillage, especially in regions of tropical and sub-tropical climate, poorly managed. farmer protection and unprotected effects of erosion.
During an El Nino, warm water gathers along the West coast of South America, so the nutrient rich water is no longer being upwelled. keeping in mind that cold water sinks and warm water rises, usually the warm water near coastal regions would not be full of nutrients compared to the cold water where the nutrients fall. therefore, more fish will be located or migrate to areas of this nutrient rich cold water instead. So, many fishermen would not have high yields of fish ultimately affecting their way of life and money. also a lot of these fish that remain at the surface would not be as healthy or nutrient rich.
hope that helps! :))
