Which of these statements about succession is incorrect?
- A) succession is a change of species composition, community structure and function over time and space
- B) succession is usually set in motion by some sort of disturbance
- C) succession is both directional and predictable
- D) succession begins only on a bare ground
Correct Answer: D) succession begins only on a bare ground
Explanation
Succession refers to the changes that occur in the species composition, community structure, and function of an ecosystem over time and space. This process is usually set in motion by some sort of disturbance, such as a volcanic eruption, wildfire, or human activity. As a result of this disturbance, organisms that are better suited to the new conditions move in and establish themselves, replacing the previous inhabitants. This process is both directional and predictable, with each stage of succession leading to the next and culminating in a stable, climax community. Option A is a true statement about succession. Option B is also correct in that disturbance is usually necessary to initiate succession. Option C is also true, as succession follows a predictable pattern. Option D, on the other hand, is incorrect. Succession can begin on any type of ground, not just bare ground. For example, secondary succession occurs in areas where the soil has already been formed, but the previous community has been removed, such as after a forest fire. Therefore, Option D is the correct answer to this question. It is important to note that succession is a natural process that occurs over a long period of time and is influenced by many factors, including climate, topography, and biotic interactions. Understanding the process of succession is important for understanding how ecosystems change and adapt over time.
