Final answer:
The assertion that a turfgrass microclimate remains constant at equilibrium once maturity is reached is false, as microclimates are dynamic and can change due to various factors.
Step-by-step explanation:
The statement that once a turfgrass reaches maturity, its microclimate is at an equilibrium and remains constant until a different species is introduced is false. Microclimates are dynamic and can fluctuate due to various factors such as climate change, human activities, and natural disturbances. For example, drought-resistant plant species would generally thrive in warmer temperatures, while other species might decline. Over time, the grass may adapt to environmental factors: an example being mowing, which can stabilize the flowering time of grass in a mowed field. An ecosystem possesses the ability to reach equilibrium, but this state is not static and can change in response to both internal and external stimuli.
