Study Notes
Biotic and Abiotic Factors
- Biotic factors include all living organisms and their interactions within an ecosystem.
- Abiotic factors encompass non-living components such as soil, climate, and rainfall.
Key Definitions
- Humidity: Represents the concentration of water vapor present in the atmosphere.
- Temperature: Refers to the degree of heat measured in an environment, indicating how hot or cold it is.
- pH: Indicates the acidity or basicity level of a substance, important for various biological processes.
- Sunlight: The natural light emitted by the sun, essential for photosynthesis in producers.
- Rainfall: A form of precipitation that contributes to water availability in ecosystems.
- Dissolved Oxygen: A critical water quality indicator that reflects the amount of oxygen available for aquatic organisms.
- Dissolved Salt: Refers to the concentration of salts in water, influencing aquatic life.
- Turbidity: Measures water clarity, indicating the presence of suspended particles.
Ecological Roles
- Canopy Cover: Percentage of ground covered by plant foliage, impacting light penetration and habitat availability.
- Soil: Comprised of mineral particles and organic matter, serving as the foundation for terrestrial plant growth.
- Prey: Organisms caught or hunted by predators for food.
- Predator: The species that hunts and kills other organisms for sustenance.
- Competitor: Organisms that vie for similar resources, affecting population dynamics and ecosystem balance.
- Producer: Organisms, mainly plants, capable of synthesizing their own food through photosynthesis.
Consumer Levels
- 1st Order Consumer: Herbivores that primarily feed on producers.
- 2nd Order Consumer: Carnivores that consume 1st order consumers for energy.
Decomposers and Populations
- Decomposer: Organisms that break down organic waste and dead matter, recycling nutrients back into the ecosystem.
- Population: A collective of individuals of the same species inhabiting a specific area, crucial for studying ecological dynamics.
