Final answer:
The marketing environment is dynamic because it is characterized by instability and frequent change, requiring businesses to continuously adapt their strategies.
Step-by-step explanation:
The marketing environment is described as being dynamic, meaning it is constantly changing and evolving. This concept implies that the environment is unstable and short term, characterized by sudden shifts that can dramatically affect how businesses operate and market their products. The dynamism can be influenced by various factors including technology, consumer preferences, economic conditions, and social trends. As opposed to a stable and predictable environment, a dynamic marketing environment requires businesses to be agile and adaptable in their strategies.
