As they multiply, die and decompose, algae deplete the ocean’s surface layers of oxygen. Often, the large amounts of farm fertilizer that run from fields into the rivers cause algae populations to explode. The MOST LIKELY result is that

Respuesta :

The most likely result is that in such conditions would be the reduction in the number of animals, plants and fishes that were in water. 

Answer:

The population of algae in the water increases due to the excess amount of nutrients such as nitrogen and phosphorous, which are provided from the run off from the farmlands. Due to this higher nutrients, the amount of dissolve oxygen decreases drastically, and aquatic plants cannot undergo the process of photosynthesis. This directly affects the organisms that lives in the fresh water and marine ecosystem, as it will be difficult for them to survive.

Thus, the excess amount of algae in water makes it unsuitable for drinking, agricultural purpose and also leads to the reduction of aquatic species.
