biotic and abiotic factors

• biotic(living) factors

  • availability of food- more food,more chance of survival and reproduction, increasing population
  • new predators-in balances ecosystem, predator catches enough pray to survive but not enough to wipe out pop, new predator= unbalanced
• biotic (living) factors

  • new pathogen- no immunity or resistance in population so may be wipes out
  • competition-2 compete for same resources, one better adapted so outcompetes the other. may continue until there are too few species to breed successfully
• abiotic (non-living) factors

  • light intensity= increased photosynthesis=increased growth
  • temperature= increased photosynthesis
  • moisture levels= water needed for survival
  • soil PH and mineral= diff plants adapted to diff conditions
  • c02 and 02 levels= photosynthesis and respiration
