Study Notes
Ecosystem
- An ecosystem is a community of living organisms interacting with each other and their non-living environment. These interactions form a system where energy flows and matter cycles to sustain life.
- Ecosystems have biotic components (living things) like plants, animals, and humans and abiotic components (non-living things) like soil, air, and water.
Energy Flow in an Ecosystem
- Energy flow in an ecosystem is the pathway energy takes to move from one organism to another.
- It's a fundamental concept in ecological studies.
- Energy flows in a unidirectional manner.
- Energy transfer typically takes place as food energy from one trophic level to another.
Energy Flow of Ecosystem Diagram
- The diagram shows the flow of energy in an ecosystem.
- The sun provides energy to producers.
- Producers (plants) are consumed by primary consumers (herbivores).
- Primary consumers are consumed by secondary consumers (carnivores/omnivores).
- Secondary consumers may be consumed by tertiary consumers (top carnivores).
- Decomposers break down dead organisms, returning nutrients to the ecosystem.
Ten Percent Law
- This law, introduced by Raymond Lindeman, states that only about 10% of energy is transferred from one trophic level to the next.
- The remaining energy is lost as heat due to metabolic processes.
Trophic Levels
- Trophic levels are the position of organisms in a food chain, food web, or ecological pyramid based on their feeding pattern.
- The positions show a succession of energy flow.
- Most food chains have a maximum of four to five trophic levels.
Trophic Levels Diagram
- The diagram illustrates a pyramid structure showcasing the decrease in biomass (living material) as you move up the trophic levels.
- Quaternary Consumers receive the least amount of energy.
- Producers, at the bottom of the pyramid, receive the most energy from the sun.
Importance of Trophic Levels
- Trophic levels are crucial to maintaining the structure and function of ecosystems.
- They facilitate the flow of energy from producers to apex predators, demonstrating the decrease in energy at each level.
- Each trophic level is connected, building on interdependencies within ecosystems.
- Decomposers recycle nutrients, enabling producers to sustain life and maintain ecological balance.
