Study Notes

What is Ecology?

Ecology studies interactions among organisms and between organisms and their environment.
Two main components: biotic factors (living influences) and abiotic factors (nonliving components).
Ecologists employ observation, experimentation, and modeling as their primary methods.

Biosphere

Encompasses all life on Earth and every area where life exists.

Definition of Key Terms

Ecology: Focuses on organism-environment interactions.
Species: A group of similar organisms capable of breeding and producing fertile offspring.
Population: Individuals of the same species located in a specific area.
Community: Different populations coexisting in a defined area.
Ecosystem: All living organisms in an area, along with their physical environment.
Biome: Collection of ecosystems with similar climates and organisms.

Factors in Ecology

Biotic Factors: Any living component of an environment that influences organisms.
Abiotic Factors: Any nonliving component of an environment impacting interactions.

Levels of Organization

Ranges from individual species to the entire biosphere:
- Species
- Population
- Community
- Ecosystem
- Biome
- Biosphere

Ecological Study Methods

Modern ecologists utilize scientific methodology through:
- Observation: Noting and recording behaviors and interactions.
- Experimentation: Testing hypotheses under controlled conditions.
- Modeling: Creating representations of ecological processes.
