Which term describes continual change from one condition to another, with slight variation due to environmental factors?

• A. Fluctuation
• B. Criteria
• C. Plantation
• D. Ecosystem

Answer: (A)

Fluctuation describes continual change from one condition to another, with slight variation caused by environmental factors. Conditions like temperature, humidity, and sunlight naturally rise and fall over time because of daily and seasonal changes, so they’re never perfectly constant. This idea of ongoing shifts around a typical level fits fluctuation perfectly. The other terms don’t capture this idea: a criteria are standards used to judge something, a plantation is a farmed area, and an ecosystem is the whole interacting web of organisms and their environment—broader than just the changing conditions themselves.
