Faith, and John Ecology Biosphere Biome
Individual The Flow of Life Autotrophs
Producers Biodiversity What is ecology? Interactions

Circle of Life

Environment Food Chain Heterotrophs
Consumers Cycles of the Earth The Water Cycle The Nutrient Cycles Carbon
Phosphorus Biomes of the World Aquatic
Tundra Aquatic Common Link
Freshwater and Marine
75% of Earth's Surface
Life Giving
Varying Organisms
Humid and Cool Deserts Hot, Semiairid, Coastal, Cold
Less than 50 cm/ year
Specialized Vegetation and Animals
Few Large Mammals Forests Tropical, Temperate, Taiga
40 Feet Ferns
1/3 Land Area
Deforestation, Pollution,
Industrial Usage Grasslands Tropical (Savanna) and Temperate
Dominated by Grass
Expanded After the Ice Age
Savannas are 1/2 of Africa Tundra Influencing Population Immigration
Carrying Capacity
Competition Patterns of Growth Better Resources
Better chance of survival Arctic and Alpine
Coldest Biome
Nitrogen and Phosphorus
Low Shrubs, Sedges, Reindeer Mosses,
Liverworts, Grasses Treeless Plain Biodiversity helps Relationships Symbiosis
Parasitism Biodiversity Hinders Massive extinction- 1,000 times higher
Habiat loss
Climate change
Forms of polution
Invasive alien-species Succession Ecological Succession

Primary Succession

Secondary Succession

Allogenic Succession Advantage over other species Use more energy then all multicellular species combined Human Activity Biggest source of environmental change Agriculture Farming began 11,000 years ago Allowed towns and cities Domesticated animals Ecological changes Forest Resources Building material and fuel Removes CO2 Produces O2 Provides habitats Prevents soil erosion Boosts ecosystem productivity
Protection of Water
Nutrient storage
Pollution breakdown
Climate stability
