Study Notes
Producers and Consumers
- Producers/Autotrophs: Organisms that create their own nourishment, primarily through photosynthesis or chemosynthesis.
- Consumers/Heterotrophs: Organisms that obtain nourishment by consuming other organisms, including herbivores, carnivores, and omnivores.
- Herbivores: Organisms that exclusively eat plants.
- Carnivores: Organisms that primarily consume flesh.
- Omnivores: Organisms that eat both plants and animals.
Energy Production
- Photosynthesis: Process by which autotrophs use light energy to synthesize carbohydrates from carbon dioxide and water.
- Chemosynthesis: Process by which some autotrophs use chemical energy to produce carbohydrates, often in the absence of sunlight.
Ecosystem Dynamics
- Keystone Species: Species that have a disproportionate impact on their ecosystem, influencing the structure and health of the community.
- Detritivores: Organisms that break down organic matter into smaller compounds, playing a crucial role in nutrient cycling.
- Decomposers: Organisms that decompose dead organic material, returning nutrients to the soil and supporting plant growth.
Ecology and Biogeochemical Cycles
- Ecology: The scientific study focused on the relationships between living organisms and their environment.
- Biogeochemical Cycle: The natural pathway through which elements and compounds (e.g., nutrients) circulate through both living (biotic) and geological (abiotic) components of the ecosystem.
- Hydrologic Cycle: Also known as the water cycle, it describes the continuous movement of water within the Earth and atmosphere.
Biotic and Abiotic Factors
- Biotic Factors: Living components of the ecosystem, such as plants, animals (e.g., deer, eagles, frogs), and fungi.
- Abiotic Factors: Non-living components that influence the ecosystem, including sunlight, soil, water, wind, temperature, and snow.
- Mass of living organisms in an area is referred to as Biomass.
Key Vocabulary Definitions
- Specialist: Organisms that have a narrow ecological niche, often relying on specific resources.
- Generalist: Organisms that can thrive in a variety of environments and can utilize a range of food resources.
- Abiotic: Non-living influences on the ecosystem like rain, temperature, and soil.
Additional Notes
- Understanding the interactions between biotic and abiotic factors is crucial for studying ecosystems and environmental changes.
