1. How Do Populations Grow? Biology Standard 6 Population Growth

2. Group of orgs that belong to same species and live in a given area. Pops grow 2 ways: exponential/logistic Populations

3. When an org has ‘ideal’ conditions for growth (lots of food, room for babies, protection, no competition) Exponential Growth

5. Controlled growth and reproduction. Limited! Logistic Growth

6. Size of a pop that can survive “healthfully” in a given area. Over c.c., death/disease occur Carrying Capacity

7. Pop increases, births and immigration > deaths and emigration. Population decreases, deaths and emigration > births and immigration. When a pop is stable, births and immigration = deaths and emigration Pop. Growth Rules
