Biodiversity Big Ideas

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

Biodiversity (click for video) 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) 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
