Presentation transcript:

INTRODUCTION I. Terms A. Ecology 1. Definitions

ECOLOGY => scientific study of the relationship between organisms and their environment Relationship = Interactions Environment = Abiotic vs. Biotic Major division of study  ecosystem

B. Hierarchy of Ecology

1. Abiotic Potential = ?????????? 2. Biotic Potential  Molecules to Organisms

3. Populations  Biosphere

3. Populations  Biosphere

Biomes are areas defined by the plant and animal life adapted for a particular biotic region.

C. Why Study Ecology? 1. History

a. Willdenow and Humboldt (early 1800’s) said similar climate = similar plant forms b. Haekel (1866) coined the term “ecology” c. Warming (early 1900’s) related plant morphology and physiology to biogeography d. Lindeman (1940’s) traced energy flow through a lake community (ecosystem ecology) e. Carlson (1960) wrote Silent Spring

II. Related Fields

III. How to study Ecology? A. Scientific Method

B. Process of Reasoning 1. Inductive 2. Deductive

C. Steps of the Method
