Question

Self-thinning (choose any/all that apply): A) is an example of intraspecific competition B) is an example of interspecific competition C) results in increased individual biomass D) results in decreased density E) results in increased density F) follows a -3/2 power function for the relationship between density and biomass G)results in mortality of individuals under favorable growth conditions H) results in decreased individual biomass

Answer 1

Self-thinning rule isalso called – 3/2 power rule or Yoda’s law.

It defines the relationship between average plant biomass to density when density dependant mortality occurs i.e, density of the populations decline as the biomass increases. The interactions among individuals and between species follow self thinning rule.

therefore, true statements- B, C,D, F, G.
