Impact of Environmental Change Essential Question: How will environmental change affect the stability of an ecosystem?

What is an Ecosystem?

What Determines Stability? Species diversity (aka Biodiversity) Feeding Relationships Between Organisms Matter and energy cycling Biogeochemical cycles Food webs

Why is the Food Web Limited?

What Affects Ecosystem Stability? Invasive species (i.e. Kudzu Invasion) Dominant species (i.e. Grass, Insects, etc.) Keystone species (i.e. Sea Otters) Storms (i.e. Irma Destruction) Fire (i.e. California Wildfire 2017) Flood (i.e. Texas Neighborhood) Drought (i.e. Cape Town Drought )

What Affects Ecosystem Stability? Overgrazing (i.e. leads to drought) Human Activity (i.e. Cities, roads, bridges, overharvesting, overfishing, stupidity, etc.)

How will environmental change affect the stability of an ecosystem? Essential Question How will environmental change affect the stability of an ecosystem?
