Succession

  • describe primary succession, from colonisation by pioneer species to climax community
  • recall that at each stage in succession, certain species may be recognised which change the environment so that it becomes more suitable for other species with different adaptations (to include that the new species may change the environment in such a way that it becomes less suitable for the previous species)
  • explain that changes that organisms produce in their abiotic environment can result in a less hostile environment and change biodiversity
  • recall that conservation of habitats frequently involves management of succession
  • show understanding of the need to manage the conflict between human needs and conservation in order to maintain the sustainability of natural resources
  • evaluate evidence and data concerning issues relating to the conservation of species and habitats and consider conflicting evidence
