Chrysanthemum flowers turn brown due to a variety of reasons, including exposure to extreme temperatures, lack of water, or fungal diseases. Overwatering or underwatering can also cause the petals to turn brown. Additionally, exposure to pollutants or chemicals in the environment can lead to discoloration in the flowers. It is important to properly care for chrysanthemum plants by providing them with adequate water, sunlight, and a healthy environment to prevent browning of the flowers. **

Wreaths or arrangements made of artificial flowers are not allowed in cemeteries because they can be harmful to the environment. Artificial flowers are typically made of non-biodegradable materials like plastic, which can take hundreds of years to decompose. These materials can also release toxins into the soil, affecting the ecosystem of the cemetery. To maintain the natural beauty and integrity of the cemetery grounds, many cemeteries have policies in place that only allow for the use of biodegradable materials for floral arrangements. **

The correct preposition to use with "cemetery" is "at the cemetery." This is because "at" is used to indicate a specific location or position, which is the case when referring to a cemetery. "On the cemetery" and "onto the cemetery" are not correct because they imply being physically on top of the cemetery, which is not the intended meaning. "To the cemetery" could be used when referring to going to the cemetery, but "at the cemetery" is the most commonly used preposition in this context. **

An artificial lake is typically filled by diverting water from a nearby river, stream, or reservoir through the use of a dam or other water control structures. Once the lake is filled, the water can be used for irrigation by pumping it out of the lake and distributing it through a network of canals, pipes, or other irrigation systems to the surrounding agricultural fields. This allows for a controlled and efficient distribution of water to the crops, helping to support agricultural production in the area. **
