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

• Biodiversity?– Variety of Species– Genetic variation within a species– Variety of Habitat
• Sustainability?– Stable/successful
• Relationship?– More Biodiversity, More Sustainable– Less Biodiversity, Less Sustainable
Ecological Succession (click for video)
• Ecological Succession– 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
