What are three basic types of survivorship curves.
They are type l, type ll, and type ll.
What is a cohort?
It is the surviving population.
Is r-selected and K-selected more of a spectrum or are they one or the other type of thing?
They are more a spectrum.
Are caddisflies more r-selected or K-selected and why?
They are more r-selected because they have high rates of reproductivity that fluctuate.
If a population of bugs keeps fluctuating at a constant rate then what type of survivorship curve is it? Also it is more r-selected or K-selected?
It is type lll and it is r-selected.
