impacts on the biosphere
DESCRIPTION
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. - PowerPoint PPT PresentationTRANSCRIPT

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.

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

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

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

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.
