Transcript

  • 1. The arrangement or patterning of communities into parallel or sub-parallel bands is known as zonation. Zonation in biomes are in latitudes and climate Zonation in plants can be in altitude.
  • 2. Gross productivity is low. Energy lost through community respiration is low. Soil becomes better structured and more fertile. Gross productivity by producers increases. Diversity increases. Net productivity increases. In climax population GPP, NPP and diversity stabilizes
  • 3. If the value of P/R is 1, then it is a steady state community. If the value of P/R is greater than 1, then biomass accumulates. If the value of P/R is less than 1, biomass is depleted.
  • 4. A CLIMAX COMMUNITY is an ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment. Ecosystems with more feedback mechanisms are more stable than simple ecosystem.
  • 5. Greater biomass Higher levels of species diversity More favorable soil conditions Better soil structure Lower pH Taller and stronger-living plant species More K-strategists/fewer r-strategists Greater community complexity and stability Greater habitat diversity Steady-state equilibrium
  • 6. A Plagioclimax community is an area or habitat in which the influences of the human race have prevented the ecosystem from developing further. All human activities ( agriculture, hunting, clearance, burning and grazing ) create a plagioclimax by arresting succession.
