1: What is N?
N= Population size
2: What is r? What is the equation for r?
r is growth rate r=(Births-Deaths)/N
3: What did Darwin realize about elephants and their reproductive rate?
He realized that elephants reproduce slowly and if they reproduce at that rate there could be 15 million elephants
4: What is K?
K is carrying capacity is the maximum population an ecosystem can support
5: What is the equation for exponential growth (j shaped curve)?
r=dN/dT
6: For logistic growth, what changes from exponential growth?
(K-N)/K is added to the equation
7: What happens if r is bigger than 0?
Exponential growth occurs
8: What is an r selected species? Give an example.
It is species that grow as fast as they can an example is a frog with no fish around it
9: What is a K selected species? Give an example.
It is when the growth rate is slow an example is chameleon
10: What kind of selected species are humans?
We are a K selected species
