1. Biodiversity Big Ideas

2. Biomes & Habitats (click for video)
Different climates = Different variety of organisms
Organisms must be adapted to an environment to survive there.
Microhabitats
School Yard
Rotten tree trunks
Terrestrial (land)
Desert
Rainforest
Grassland
Taiga
Deciduous Forest
Tundra
Aquatic/Marine (water)
Ocean/Saltwater
Fresh water

Variety of Species
Genetic variation
within a species
Variety of Habitat
Sustainability?
Stable/successful
Relationship?
More Biodiversity, More Sustainable
Less Biodiversity, Less Sustainable

4. Ecological Succession (click for video)
Gradual replacement of organisms with larger, more complex organisms
Grasses  Bushes  Trees
Insects  Rabbits  Deer
Climax Community: Forest
Primary Succession
Begins without soil; rock
Promoting Events: Volcanic eruption, weathering
Pioneer Species: Lichen
Secondary Succession
Begins with soil
Promoting Events: Fire, Construction, Hurricane, Landslide
Pioneer Species: Grasses
Microhabitat: Garden
Invasive Species: Weeds
