Which of these sequences best places the stages of ecological succession in order from earliest to latest?

A. Climax community, thin soil, disturbance, pioneer species
B. Thin soil, disturbance, climax community, pioneer species
C. Pioneer species, disturbance, thin soil, climax community
D. Disturbance, thin soil, pioneer species, climax community

Answer :

Final answer:

The correct order of ecological succession stages is disturbance, pioneer species, thin soil, and climax community, making option D the right choice. Disturbance leads to the growth of initial species that improve soil, eventually contributing to a stable ecosystem. Understanding these stages helps in grasping how ecosystems recover and develop over time.


Explanation:

Understanding Ecological Succession


The correct sequence for the stages of ecological succession from earliest to latest is:



  1. Disturbance

  2. Pioneer Species

  3. Thin Soil

  4. Climax Community


Thus, the answer is D: disturbance, thin soil, pioneer species, climax community.


During ecological succession, a disturbance (like a fire or human activity) creates an environment where new life can begin. This leads to the establishment of pioneer species, which are the first organisms to colonize the area, helping to improve soil quality and create conditions for more diverse species. Over time, as thin soil becomes enriched, a more complex community forms, ultimately stabilizing into the climax community, which is indicative of a mature ecosystem.
