1. Warm up: Put up phones and answer this question
How is fecundity important for populations? Why does it affect those with long gestational periods?

2. Biological Population & Community
Order
Uniform
Random
Clumped
Characteristics

3. Order
Biosphere
Biome
Ecosystems
Communities
Populations
Individuals

4. Uniform
Bottom:
Found in populations which distance between neighboring individuals are maximized
competition for resource
territoriality (penguins)

5. Random Bottom Little interaction among those in population
In habitats where environmental conditions and resources are consistent
Characteristic among organisms that lack strong social interactions
Dandelion seeds among wind dispersion

6. Clumped Bottom: Against predation and for trapping animals (lions)
Found in environments with patchy resources
Most common
Clumped together around crucial resources (watering hole)
Might cluster because of social factors (wildebeest)
Prey animals likely clump so they can hide and detect prey (duck)
Offsprings can’t move by themselves from habitat (chimps)
Threatened/ endangered organisms

7. Characteristics Physical appearance Species diversity
Size, distribution of population and species
Species diversity
Number of different species
Species abundance
Number of individuals of each species
Niche structure
Number of ecological niches; how they resemble or differ from each other’ species interaction
