Succession is a process, with each new community paving the way for the next true or false

The correct answer for this question is TRUE

Ecological succession is the process of change in structure of an ecological species by pre-existing community over time. We can say that in ecological succession, each new community is paving a way for new community. The different types of ecological succession exists during different phases of an ecosystem, and depends on how developed that ecosystem is. Succession that begins in new habitat, uninfluenced by pre-existing community is called primary succession whereas succession that follows disruption of a pre-existing community is called secondary succession.
