Which plant grows in fields and is known for its adaptability?

Sumac is the correct answer due to its remarkable adaptability, especially in various field conditions. This plant is known for thriving in a wide range of habitats, including dry, rocky, and disturbed areas. Its ability to colonize and establish itself in less hospitable environments allows it to successfully grow in fields, where it can quickly spread and cover large areas.

Additionally, sumac is a hardy plant that can tolerate different soil types and moisture levels, making it a resilient choice in ecosystems that may experience variations in climate or human activity. This adaptability not only supports its growth in fields but also contributes to its role in erosion control and providing habitat for wildlife.

In contrast, the other plants listed have more specific habitat preferences or adaptations that limit their growth in field environments.
