1.Ecosystems

2. What is an Ecosystem?
Biological Environment
Consists of Organisms
Live in a particular area
Includes Non-living organisms
Physical Components of the Environment
Organisms Interact
3. Population
What is a population?
All the organisms
Belong to same species
Live in the same geographical area
4. Community
What is a community?
Group of interacting species
Share a populated environment
Include living and non-living organisms
5. Interactions
Organisms interact in various ways
May be beneficial
Shelter, Food, Safety
May not be beneficial
Harmful to the organism
Harmful to
other organisms
6. Biotic Factors
Living Organisms
Plants
Animals
Fungi
Protista
Bacteria
7. Abiotic Factors
Non-living Organisms
Affect living organisms
Environmental factors such as habitat
Pond, lake, ocean, desert, mountain
Weather Factors
Temperature, cloud cover, rain, snow hurricanes
8. What is a Food Chain?
Shows how each living thing gets food
Starts with Sun/plant life
Ends with an animal
9. Consumers
Cannot make their own food
Feed on other plants/animals
Three types of consumers:
Herbivores- Eat only plants
Carnivores- Eat other animals
Omnivores- Eat both plants and animals
10. Producers and Decomposers
Producers
Plants
Use light energy from sun
Produce food from CO2 and Water
Decomposers
Bacteria and fungi- Feed on decaying matter.
11. Food Web
Shows all feeding relationships
between organisms living in an ecosystem
More complex the a food chain
More accurate then food chains
Several food chains joined together
Organisms depend on more than one species for food
12. Food Web Cont.
13. Environmental Changes
Land-Use Change
Storm Severity
Species Behavior
Population Growth Rate
Evolution
14. Great Lakes Region
Sand dunes, coastal marshes, rocky shorelines
Lake plain prairies, savannas, forests
Four Seasons
Summer and Fall
Spring and Winter
Great Beaches
15. Food Web Assignment
Create your own food web
Worth 10 points
Must consist of at least 10 organisms
Must be Accurate
Be creative
Have fun with it!
