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

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

16 Quick review

17  What is the portion of the earth that supports life called?
Give 2 examples of abiotic factors. What do you call the role a species plays in its environment? Biosphere Niche

18 What is formed by several populations that interact with each other?
What do you call a community and its abiotic factors? List the levels of biological organization from smallest to largest. Community Ecosystem OPCEB
