1. Introduction to Ecology
Organisms and Their Environments

2. Ecology
The study of the interactions of organisms and their environment

3. Levels of Biological Organization

4. Part of earth that supports life
Includes communities & abiotic factors
Groups of populations in a region.
A single organism
Group of organisms of same species

5. Niche vs. Habitat

6. Habitat
The place where the organism lives.
Like an address

7. Niche
The role a species plays in a community.
Like an occupation

8. Niche
Includes the space, food, and other conditions the organism needs to survive

10. NOTE:
Several species may share a habitat, but the food, shelter, and resources of that habitat are divided into separate niches.

part of the tree
Yellow-Rumped Warbler
Feeds in the lower part of the tree and
at the bases of the middle branches
Cape May Warbler
Feeds at the tips of branches
near the top of the tree
Spruce tree

12. What shapes an Ecosystem?
Biotic & Abiotic Factors
Community Interactions
Ecological Succession

13. Biotic Factors All the living organisms that inhabit an environment.
Bio = life tic = pertaining to.
EX: Animals, plants, fungi, bacteria, protists

14. Abiotic Factors All the non-living parts of the environment
A = not/without, bio = life
Examples = soil, rocks, water, minerals, temperature

15. List all of the biotic & abiotic factors
