Outline one climatic and one edaphic (soil) factor which affect the final climax community in an ecosystem.
Climatic:
amount of precipitation / insolation / (mean) temperature;
limit primary productivity/rate of photosynthesis that will determine the available biomass/food base/on which climax community will depend;
Edaphic:
soil depth / mineral content/amount of N/P/K / soil compaction/aeration / soil particle size / balance between clay, silt and sand / percolation rate / soil pH;
determine the particular vegetation types/plant species adapted to those conditions that support the climax community;
Marking guidance:
Award up to [2 max] for climatic factor and up to [2 max] for edaphic factor.
