(i) A and B are equally stable.
(ii) A has more species than B.
(iii) A and B have equal diversity of species
(vi) B is more stable than A
`{:(,"Year","Year","Year","Year"),(,2009,2010,2011,2012),("Biomass",A=1000,A=800,A=950,A=1000),(("Total"),"Units","Units","Units","Units"),(,B=1000,B=100,B=500,B=100),(,"Units","Units","Units","Units"):}`

Options

A. One
B. Two
C. Three
D. None

Answer

A

Explanation

A stable community will be resistant to occasional natural disturbances and does not show two much variatoin in productivity from years to years. Areas with more species show less year variation in total biomass.
Thus (i) False = A is more stable than B.
(ii) is false , (iii) is False : (iv) is False
