Final answer:
The correct sequence reflecting increasing cultural intensity of turfs is utility, lawn, sports, since sports turfs require the highest level of maintenance to ensure optimal conditions for activities.
Step-by-step explanation:
In the context of cultural intensity regarding turfs, we can infer that the sequence that reflects increasing cultural intensity would be utility, lawn, sports. The reasoning behind this order is that utility turfs are typically areas with grass that are low-maintenance and are there to cover the soil and provide basic aesthetic value with minimal care. Lawn turfs, on the other hand, see a moderate level of care and maintenance, as residential and commercial lawns are often managed to achieve a certain aesthetic standard, but they are not subjected to the same stress as sports turfs. Finally, sports turfs require the highest cultural intensity as they must maintain a pristine condition to facilitate various sporting activities. They are regularly mowed, watered, and treated with fertilizers and pesticides to ensure they can withstand heavy use and provide a safe, uniform playing surface.
