Answer: 2 and 3
Notes: Succession is a process of ecological change in which a series of natural communities are established and then replaced over time. It involves an increase in productivity, a shift of nutrients, an increase in diversity of organisms with an increase in the niche development. However, it does not lead to a gradual decline in the complexity of food webs, instead the complexity often increases with progressing succession.
