The plants that allow them to compete with each other D. The long roots help the prairie plants compete for water. Therefore , D. The long roots help the prairie plants compete for water is correct .
Prairie plants have long roots that can reach deep into the soil to access water that is not available to plants with shorter roots.
This is especially important during periods of drought, when water is scarce.
Prairie plants also have a variety of other adaptations that help them survive in dry conditions, such as deep taproots, waxy leaves, and the ability to close their stomata (leaf pores) to reduce water loss.
Here are some other ways that prairie plants compete with each other for water:
Developing a dense root system: Prairie plants often have a dense root system that can spread out over a large area.
This helps them to absorb more water from the soil.
Growing tall: Taller prairie plants can shade out shorter plants, reducing their access to sunlight and water.
Producing allelopathic chemicals: Some prairie plants produce allelopathic chemicals that can inhibit the growth of other plants.
These chemicals can be released into the soil or the air.
Competition for water is a major factor that determines the composition and structure of prairie plant communities.
Prairie plants have evolved a variety of adaptations to help them compete for water in this harsh environment.
