1. Ecology
Biomes

2. Lets Review! Biotic Abiotic Ecosystem 4 abiotic factors
Organism: two types
Species
Population
Community
Biome

3. How many species and how many organisms?
Brown bear, western canada

4. Individual (one organism)? Population? Community?

5. Habitat A habitat is a home or location where an organism lives.
Habitats can be very small or very big!
Example of a small habitat and example of a large habitat

6. Habitat In a habitat, an organism must find 1. Food 2. Water
3. Shelter
4. Space

7. Niche A niche is an organism’s role (job) in the ecosystem
It includes what it eats, where it lives, and what it does

8. Niche
For example:
What is the niche of a farmer?
-to grow food

9. Niche
What is the niche of a carpenter?

10. Niche

human community work 

11. Niche What is the niche of a beaver? It includes: -cutting down trees
-building a dam
-building a lodge to live in
-raising a family of beavers
-chewing bark and wood
Building a dam to flood an area and make a pond

12. Niche
Chipmunks
-spreaders: they gather and store seeds, and acorns and berries get left behind or forgotten; seeds and berries will grow into new plants

13. Niche Blackberry Bush -serves as food for animals
-roots help hold down the soil and help stop erosion
-serve as shelter and nesting places for birds and other animals

14. Niche No two species have the same niche in an ecosystem For example:
-moves pollen from flower controls insect population
to flower eats carpenter ants
-chisels them out of trees with its beak
So both birds, but have different roles in a community

15. Adaptations?
