Study Notes
Earth as a Spaceship
- Earth likened to a vast spaceship with life support systems consisting of organisms and solar energy.
- Organisms produce oxygen, transfer energy, and efficiently recycle nutrients.
Ecological Principles and Concepts
-
Environment: External forces and conditions affecting organisms, categorized into two types:
- Natural Environment: Includes terrestrial and marine ecosystems.
- Cultural Environment: Results from human activities influencing surroundings.
-
Environmental Science: Study focused on environmental processes and issues stemming from human-environment interactions.
-
Ecology: Examines relationships between organisms and their environment, including interactions with physical surroundings and species interrelations.
-
Ecosystem: A unit composed of living (biotic) and non-living (abiotic) components, including bacteria, plants, animals, water, air, soil, and climate.
Components of Ecosystem
-
Biotic Factors:
- Producers (Autotrophs): Organisms like plants that create their own food via photosynthesis.
- Consumers (Heterotrophs): Organisms, such as animals, that cannot generate their own food and rely on autotrophs.
- Decomposers: Break down dead material and waste, crucial for nutrient recycling; includes bacteria and fungi.
-
Abiotic Factors:
- Light
- Water
- Atmosphere
- Ocean conditions
- Climate
- Fire
- Temperature
