Which of the following is not a characteristic of weeds?
Answer Details
The answer is "seeds have short period of viability". Weeds are known for their ability to produce numerous seeds and have an aggressive growth habit, which allows them to outcompete other plants for resources. They may also be resistant to trampling, meaning that they can survive even when repeatedly stepped on or otherwise disturbed. However, the viability of their seeds can vary greatly depending on the species, and some weed seeds can remain viable in the soil for many years. So, the option that is not a characteristic of weeds is "seeds have short period of viability".
