3. Population: a group of organisms of one species in the same area.

4. Biotic (prefix Bio means life)– any living thing

5. Abiotic – non living thing

6. Overpopulation– excess number of same species living together in the same place.

7. Exponential Growth : when population growth expands or increases at a constant pace

8. Limiting Factor : a factor that inhibits population growth of a species population.

9. Logistic Growth :  is when the population growth rate decreases as the population reaches carrying capacity.
Accounts for limiting factors

10. Competition : When organisms’ attempt to use the same resources
Competition : When organisms’ attempt to use the same resources. (food, shelter, water)

11. Carrying capacity :  the maximum, number of organisms of a particular species that can be supported indefinitely in a given environment.

12. Scale : the structural change in size of a population

13. Reflection:
Now in your notebook on page 1 answer the Essential Question using at least 5 of your vocabulary words in the paragraph.

14. Community : a group of interacting populations of species living in the same area.

15. Biodiversity : variety of life on Earth.

16. Ecological diversity: is the variation in the ecosystems found in a region.

17. Habitat : the natural home or environment of an animal or plant.

18. Niche : an organism's role in an ecosystem.

19. Population Distribution :  the arrangement or spread of people living in a given area.

20. Population Density : is a measurement of population per unit area or unit volume

21. Resource partitioning : When species divide a niche to avoid competition for resources
