B
Explanation
The question asks for the fundamental reason why succession, a process of ecological change, occurs. To understand this, we should explore each option:1. **Option A** suggests that ecosystems are static and unchanging. This statement is incorrect. Ecosystems are dynamic and constantly evolving due to various biotic and abiotic factors.2. **Option B** states that ecosystems naturally evolve and change over time, with species adapting to and altering their environments. This is accurate as ecological succession is the natural process through which ecosystems change and develop over time. Species interact with each other and their environment, leading to gradual changes in the ecosystem's composition and structure.3. **Option C** implies that human intervention is necessary for any change in ecosystems. This is not true in the context of natural succession, as ecosystems can and do change without human interference.4. **Option D** claims that ecosystems change only due to climatic factors. While climate is a significant driver of ecological change, it's not the sole factor. Succession is influenced by a variety of factors including, but not limited to, species interactions, soil composition, and natural disturbances.
