What term describes the gradual change in plant types in an area over time?

• A. Succession
• B. Dispersion
• C. Speciation
• D. Mutation

Answer: (A)

The term that describes the gradual change in plant types in an area over time is succession. Succession is a natural process in ecology through which ecosystems change and develop over time. It typically involves a series of stages in which different species of plants and animals colonize an area, leading to a shift in the habitat’s composition and structure. For example, after a disturbance like a forest fire, early-successional species such as grasses and weeds may establish themselves first, followed over time by shrubs and ultimately, trees as the ecosystem matures. This process can be categorized into primary succession, which occurs in lifeless areas where soil has not yet formed, and secondary succession, which occurs in areas where an ecosystem has been disturbed but soil and some organisms still exist. Understanding succession is crucial for ecologists studying biodiversity, habitat restoration, and the impacts of climate change on ecosystems.
