Question

Quizplus · Accepted Answer

Communities evolve to have greater biomass and species richness through a process called succession, which is the gradual change over time in the species composition of a community towards a more complex, diverse and stable state. This process usually starts with pioneer species that colonize a disturbed or barren area and gradually give way to more diverse and complex species as the environment becomes more suitable and resources become more available. Overall, succession leads to an increase in biomass and species richness, as well as to the development of more complex and stable ecological interactions, such as competition, predation, and mutualism.
