Study Notes
Ecosystem
- An ecosystem comprises a community or group of living organisms interacting in a specific environment.
- Tropical forests serve as an example of ecosystems, consisting of trees, plants, animals, insects, and microorganisms.
- Organisms within an ecosystem interact with one another and are influenced by physical elements (e.g., sunlight, temperature) and chemical components (e.g., oxygen, nutrients).
Global Ecosystem
- The global ecosystem is a systematic, integrated entity made up of various components.
- Essential components include biotic elements (living organisms) and abiotic elements (non-living factors).
- Ecosystems require five basic components for survival: energy, mineral nutrients, water, oxygen, and living organisms.
- The primary source of energy for ecosystems is solar energy.
Pedosphere
- The pedosphere is the outermost layer of Earth made up of soil.
- It is formed through dynamic interactions between the atmosphere, biosphere, lithosphere, and hydrosphere.
- The pedosphere acts as the foundation for terrestrial life and is subject to ongoing soil formation processes.
Earth's Subsystems
- Earth's subsystems are referred to as "spheres" and include both abiotic and biotic components.
- Four major spheres exist: lithosphere (land), hydrosphere (water), atmosphere (air), and biosphere (life).
- These spheres intersect to influence the overall functioning of the planet's ecosystems.
