|
I understand the concept of carrying capacity and how limiting factors influence this, and use quantitative analysis to determine the carrying capacity
|
I can identify and define the difference between interspecific and intraspecific competition.
I can explain how limiting factors create a carrying capacity
I can identify if a limiting factor is density-dependent or density independent.
