  • One which is easily disturbed and that lacks resilience to change (7, 11)
  • Plants which invade bare ground, hardy and adapted to harsh environments (7, 7)
  • Process, by which salts are drawn to the surface by strong evaporation (12)
  • Small specific locations e.g. under a leaf (13)
  • The capacity to endure, in ecology the word describes how biological systems remain diverse and productive over time. (14)
  • The process in green plants by which carbohydrates are synthesised from CO2 and water using light as an energy source, and producing oxygen as a by product. (14)
