1: What is N? N is population size.
2: What is r? What is the equation for r?
r is growth rate.
The equation for r is: r=(births-deaths)/N
3: What did Darwin realize about elephants and their reproductive rate?
Darwin realized about elephant and their reproductive rate is that if you let elephants keep breeding from 30 years old to 90 years old, they reproduce to have 3 pairs of young.
4: What is K? K is carrying capacity.
5: What is the equation for exponential growth (j shaped curve)?
dN/dt=r N
6: For logistic growth, what changes from exponential growth? (K-N)/K will added to the exponential growth.
7: What happens if r is bigger than 0?
If the r is bugger than 0 then, it will show exponential growth.
8: What is an r selected species? Give an example.Species that loves to grow as quickly as it can.
9: What is a K selected species? Give an example.
Growth rate of these species is slow, and the offspring are cared for.
10: What kind of selected species are humans?
We are a K selected species
