• Biodiversity
• Extinction
• Endangered Species
• Threatened Species
• Habitat Fragmentation
• Edge Effect
• Habitat Degradation
• Acid Precipitation
• Ozone Layer
• Exotic Species
Biodiversity: the variety of species in an area
Endangered vs. Threatened Species
Endangered Species = numbers become so low that extinction is possible.
Threatened Species =A population is likely to
become endangered.
Habitat Fragmentation: separation of wilderness areas from
other wilderness areas.
Edge Effect: different conditions along the boundaries of an
ecosystem.
Habitat Degradation: damage to a habitat by pollution.
Acid Precipitation: rain, snow, sleet and fog with low pH values.
Ozone Layer: absorbs some of the ultraviolet waves striking the
atmosphere.
Exotic Species (aka… invasive species): species not native to that area.
