Presentation transcript:

Ecology Ecology is the study of interactions among organisms and their environment

What is meant by an ecosystem? An ecosystem is part of a Biome that includes biotic and abiotic factors.

Abiotic vs. Biotic https://www.youtube.com/watch?v=GlnFylwdYH4 Can you identify 3 biotic and abiotic factors? What is the difference between biotic and abiotic?

Can you identify our 8 terrestrial biomes on earth? Tundra Permeant Ice Temperate Rainforest Tropical Rainforest Grassland Desert Temperate Deciduous Forest Boreal Forest

What are the two main factors that determine the characteristics of each Biome on our earth? Temperature Precipitation

How do humans influence our ecosystems? Human Activities that threaten Biodiversity What is meant the carrying capacity of our biosphere? The earth cannot indefinitely support the ever increasingly population We would exceed to carrying capacity for our biosphere What have we done as humans to increase our carrying capacity for our Earth? Technology and science to increase food production https://www.youtube.com/watch?v=2RC3Hsk90t8

Your turn - Brain storm, in groups, ways that humans have impacted our ecosystems.

Air pollution Smog Oil being spilled into the Pacific Ocean

Agriculture Soil compaction Fertilizer use Soil degradation Monocrop vs Polycrop Animal agriculture (beside)

urbanization Destruction of habitat Fragmentation Deforestation Urban sprawl (Mexico)

Water pollution

Overexploitation Deforestation in BC Cell Phones Oil

Next class… Groups of 4 or 5 In your group, choose one of the 8 biomes on our earth Each member of your group will choose one impact that humans have on the biome. Research an article that speaks to your ‘impact’ or topic Morven library website
