Study Notes
Ecology Fundamentals
- Basic Unit of Ecology: Organism is the smallest unit, critical for understanding ecological interactions.
- Biotic Components: Includes living organisms like bacteria, while abiotic components include sunlight, water, and soil.
Ecological Processes
- Evolution: The process where organisms change over time, leading to adaptations within species.
- Ecological Succession: The gradual process of change in species structure in a community, starting with pioneer species.
Energy Flow in Ecosystems
- Food Chains: Represent energy flow from producers (typically plants) to consumers and decomposers. Energy flows from producers to consumers.
- Primary Producers: Mainly plants, which convert sunlight into energy via photosynthesis.
Symbiotic Relationships
- Fungus and Plant Roots: The symbiotic relationship known as mutualism benefits both organisms.
- Types of Interactions: Commensalism involves one organism benefiting while the other is unaffected; parasitism harms one while benefiting another.
Ecosystem Dynamics
- Niche Concept: Refers to the role of an organism within its ecosystem, involving its interactions with biotic and abiotic factors.
- Biodiversity: Represents the total number of different species in an area and is crucial for ecosystem health.
Environmental Influences
- Factors Influencing Distribution: Climate, soil, and topography collectively impact where organisms are found.
- Habitat Fragmentation: Can lead to decreased genetic diversity among species, negatively affecting population resilience.
Coral Reefs and Climate Change
- Coral Bleaching: A likely consequence of climate change, indicating stress in coral reef ecosystems due to rising temperatures.
Protected Areas and Biodiversity
- Challenges in Conservation: Habitat fragmentation and inadequate funding can limit the success of protected areas in preserving biodiversity.
Keystone Species
- Role of Keystone Species: They are crucial for maintaining the structure and function of their ecosystem, significantly impacting overall balance.
Pollution and Aquatic Ecosystems
- Consequences of Pollution: Can lead to decreased fish populations and has detrimental effects on aquatic biodiversity.
Biodiversity and Stability
- Biodiversity vs. Ecosystem Stability: Higher biodiversity generally contributes to greater ecosystem stability and resilience against disturbances.
Sustainable Agriculture
- Benefits of Sustainable Practices: Reduces water pollution and enhances biodiversity while mitigating issues such as soil erosion.
Invasive Species
- Impact of Invasive Species: They can outcompete native species, leading to ecological imbalances and decreased biodiversity.
