What is the term that describes a steady and stable community?

• peak community

• turf community

• climax community

• disturbed community

What is the distinction between a zone of tolerance and a limiting factor? 

• Limiting factors are biotic or abioitc things that limit growth, range of tolerance defines the factors in which an organism can survive. 

• The Range of tolerances are biotic or abioitc things that limit growth, limiting factors defines the factors in which an organism can survive. 

• They define the same idea

• Both refer to the growth of species populations, limiting factors are only biotic factors, range of tolerance defines abiotic factors
