What would You predict about animals during stage 2?

During stage 2 of ecological succession, which typically follows initial colonization by pioneer species, I would predict that animal populations will begin to diversify and increase in number as the habitat becomes more stable and complex. The presence of more vegetation and varied food sources will attract a wider range of herbivores, which in turn can support an increasing number of predators. This stage often sees the establishment of more complex food webs and interactions among species as the ecosystem matures. Overall, animal biodiversity is likely to rise significantly during this phase.
