Impacts on the Biosphere

Impacts on the Biosphere. Learning Targets- I can:. Explain how biotic and abiotic factors determine biome classification (temperature, rainfall, altitude, type of plant, latitude, type of animals). • Compare impacts of biotic and abiotic factors on biodiversity.

Presentation Transcript

  1. Impacts on the Biosphere

  2. Learning Targets- I can: • Explain how biotic and abiotic factors determine biome classification (temperature, rainfall, altitude, type of plant, latitude, type of animals). • Compare impacts of biotic and abiotic factors on biodiversity. • Match landforms and soils (and their change over time) to biomes.

  3. Biomes • Forest • Tropical • Temperate • Boreal • Tundra • Arctic • Alpine • Desert • Hot/dry • Semi-arid • Coastal • Cold • Aquatic • Freshwater • Marine • Grasslands • Temperate • Savanna

  4. North Carolina Biomes • Aquatic

  5. Marine

  6. Forests Boreal Temperate

  7. Abiotic Factors • Climate • Temperature • Precipitation • Sunlight • Soil • Space for species activities • Nutrients; carbon, nitrogen, phosphorus • Water

  8. Biotic Factors • Plants • Animals • Bacteria • Viruses • Parasites

  9. Limiting Factors • Scarcity of water or sunlight • Lack of food/prey • Too few members of species to reproduce & pass along genetic diversity

  10. Biosphere & Biodiversity • Biosphere- all life on Earth • Biodiversity- the result of: • genetic variation within populations and • variation of populations within ecosystems

  11. Some species are developed through genetic variation as a result of isolation from one another. The Kaibab squirrel and Abert’s squirrel (different species) exist on opposite sides of the Grand Canyon.
