- Succession
- pioneer species
- the habitat starts off unsutable for life due to abiotic factors
- the pioneer will colonise the area and chnage the abiotic factors
- makes it more suitable for future species
- when the pioneers die return nutrients to the soil and environment
- can survive harsh abiotic conditions
- primary succession
- when one one had perviously inhabited
- eg no soil
- when one one had perviously inhabited
- interspecific competition
- new species arise due to more suitable abiotic conditions
- these new species outcompete the pioneers
- this repeats until the climax community is eventually reached
- each species chnages the enviromemt - previous species= less suites to conditions
- secondary succession
- eg fire or natural disaster = soil is still there
- climax community
- when speciesis richness and biodiversity = max
- when enviroment and conditions and pop are stable
- eg trees
- abiotic factors are so favourable so that it can support lots of different species
- more complex food webs
- change in the ecological community over time
- conservation - can prevent succession
