Weeds tend to compete with landscape plants and turf for what resources?

Weeds compete with landscape plants and turf primarily for essential resources such as nutrients, light, and water. These resources are crucial for plant growth, and the presence of weeds can significantly impact the availability of these resources for desirable plants.

Nutrients are necessary for plant development as they play key roles in various physiological processes. When weeds are present, they can consume a disproportionate amount of these nutrients, leaving less available for other plants.

Light is another critical resource that weeds can overshadow or block, preventing landscape plants and turf from receiving adequate sunlight, which is vital for photosynthesis and overall health.

Water is equally important, especially in periods of low precipitation or high temperatures. Weeds can absorb a significant amount of moisture from the soil, reducing the availability of water for other plants.

Thus, the combination of competition for nutrients, light, and water explains why option C is the most accurate response to the question regarding the resources that weeds compete for.
