The best model to describe this population is: A) all of these are equally good models of the given scenario. B) logistic growth. C) r-selected growth. D) exponential growth. E) density-...

What is an animal's niche? How many dimensions can a niche have? Can animals share a niche? - Answer-An animal's niche is the functional role of an organism considered in the environment in which it lives, its "job." A niche is multidimensional. No two organisms can occupy the same niche at the same time in the same place. What is a specialist vs a generalist? - Answer-A specialist fits into their environment tightly and there is no room for dealing with changes or for colonizing differ...

Density Dependent Factor - A factor that influences an individuals probability of survival and reproduction in a manner that depends on the size of the population (i.e. predation, disease, food supply) Density Independent Factor - A factor that has the same effect on a individual's probability of survival and reproduction at any populations size (i.e. hurricanes, floods, fires) exponential growth models - occurs when populations are not limited by resources. (J-curve) logistic growth mo...
