**Logistic Growth Guided reading:**

__1: What is N?__

N is the population of a 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?__

Darwin realized that if you let elephants breed for a long time, the kids of that elephant that got breeding for a while to have more than 1 kid at a time. Also how it will produce more over time and multiply.

__4: What is K?__

K caries 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 is added to the exponential growth equation.

__7: What happens if r is bigger than 0?__

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.

**Ex:**Bacteria

__9: What is a K selected species? Give an example.__

Growth rate of these species is slow, and the offspring are cared for.

**Ex**: Humans

__10: What kind of selected species are humans?__

We are the K Selected species since we care about the people surrounding us and our kids.
