Study Notes
Biological Organization
- The study of ecology is concerned with higher levels of biological organization, from atoms to the biosphere.
- Scientists utilize biological organization to understand how life is structured and functions at different levels, such as molecules, cells, tissues, organs, and ecosystems.
- Interdependence across levels, such as between cells, tissues, organs, and organisms, is crucial for understanding fundamental ecological processes, including energy flow, genetic information transfer, and species interactions.
Ecology: Etymology and Definitions
- The term "ecology" was coined by German biologist Ernst Haeckel in 1869.
- "Ecology" originates from two Greek words: "oikos" (house or family) and "logos" (study).
- Early definitions of ecology focused on the relationship of organisms with their environments, both organic and inorganic.
- Ecology is defined as the scientific study of the relationship between organisms and their environment.
Modern Meanings of Ecology
- Ecology studies the relationship between organisms and their physical, chemical, and biological surroundings.
- It is a professional science with various branches, including population, community, and ecosystem ecology.
- The term "ecology" should not be confused with "environment" or "environmentalism." Environmentalism is a political and philosophical movement advocating for environmental protection.
Distinguishing Ecology from Environmental Science
- Ecology: Focuses on the interactions between organisms and their environments, including ecosystems, populations, species interactions, energy flow, and nutrient cycling.
- Environmental Science: Is an interdisciplinary field that studies the environment as a whole, drawing on knowledge from ecology, chemistry, geology, physics, and social sciences.
- While ecology is about natural relationships, environmental science applies ecological principles, combined with other scientific knowledge, to address environmental challenges.
