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
