Answer:
B. runoff of nitrates from fertilizers applied to the golf course
Explanation:
Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.
Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.
Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".
Answer:
True. It is because pollution is caused from greenhouse gases such as carbon dioxide, which eventually affects the environment and atmosphere by raising the temperature (global warming) which is caused by the greenhouse effect.
Trees do not emit greenhouse gases. Rather, they are the natural resource that helps clean it out. However, due to deforestation, there aren't enough to combat the amount of gas that is produced at the current rate.
