In some ecosystems, succession increases the chance of disturbance. in these ecosystems,

The answer is that in these ecosystems, climax community may not occur. Ecological succession is the gradual process in which ecosystems change and develop over time, thus nothing remains the same and also the habitats are constantly changing. There are two main types of biological successions;primary succession which is an opening of a pristine habitat and the secondary succession which is a response to a disturbance.

There are ecosystems like cyclic succession that has a concept of community ecology that may result to increase chance of disturbance when climax communities may not occur. This is a pattern of a small number of species that tend to replace each other over time in the absence of large-scale disturbance, long-term physical changes in the environment and an end-state climax community with stable species compositions.

The answer is a if u read the definition it makes sense
