Answer 3

Possible Cause of Algae Growth in the Lake

The sudden growth of algae in the lake near the livestock farm could be attributed to several factors. Let's evaluate each option to determine the most likely cause:

1) Lowering water levels in the lake: A decrease in water levels can lead to an increase in nutrient concentration, which can promote algae growth. However, it is important to note that the question does not mention any change in water levels, so this option may not be the most likely cause.

2) Decreased air temperature: While temperature can affect the growth of algae, it is less likely to be the primary cause in this scenario. Algae growth is typically more influenced by factors such as nutrient availability and sunlight.

3) Gas emissions from farm equipment: Gas emissions from the equipment on the farm can potentially contribute to water pollution, but it is less likely to directly cause algae growth. However, if the emissions contain pollutants that increase nutrient levels in the lake, it could indirectly contribute to the growth of algae.

4) Introduction of organic matter from the farm: The most likely cause of the sudden algae growth in the lake is the introduction of organic matter from the livestock farm. Organic matter, such as animal waste or excess feed, can provide nutrients like nitrogen and phosphorus that promote algae growth. This is a common issue in bodies of water near agricultural activities.

Based on the information provided, option 4 seems to be the most likely cause of the algae growth in the lake near the livestock farm. The introduction of organic matter from the farm, such as animal waste or excess feed, can significantly contribute to the nutrient levels in the lake and promote the growth of algae.

Please note that without further information or analysis, it is difficult to determine the exact cause. It is recommended to conduct a thorough investigation or consult with experts in the field to accurately identify the cause of the algae growth in the lake.
