Study Notes
Ecology Vocabulary
- Biotic: Refers to the living parts of an ecosystem.
- Abiotic: Refers to the non-living parts of an ecosystem.
- Herbivore: An organism that consumes only plants.
- Carnivore: An organism that consumes only animals.
- Omnivore: An organism that consumes both plants and animals.
- Producer: An organism that makes its own food through photosynthesis.
- Consumer: An organism that relies on other organisms for food.
Ecological Interactions
- Symbiosis: A close relationship between two different species.
- Mutualism: A relationship where both species benefit.
- Commensalism: A relationship where one species benefits, while the other is unaffected.
- Parasitism: A relationship where one species benefits, while the other is harmed.
Ecological Concepts
- Ecology: The study of interactions between organisms.
- Producers: Organisms that produce their own food via photosynthesis.
- Consumers: Organisms that rely on other organisms for energy.
- Decomposers: Organisms that break down dead organic matter.
Energy Flow and Food Webs
- Food Chain: A sequence of who eats whom in an ecosystem.
- Food Web: A network of interconnected food chains.
- Energy Flow: The directional movement of energy through ecosystems.
- Trophic Levels: A hierarchy of feeding positions in a food chain.
- Energy Pyramid: A diagram showing energy flow through trophic levels.
- Biomass Pyramid: A diagram representing biomass at each trophic level.
Succession and Carrying Capacity
- Ecological Succession: A gradual change in species composition over time.
- Primary Succession: Begins in a barren area with no soil.
- Secondary Succession: Occurs in areas with existing soil and some life.
- Climax Community: A stable, balanced community of plants and animals.
- Carrying Capacity: The maximum population size an ecosystem can sustain.
- Limiting Factor: Factors that restrict population growth.
Biogeochemical Cycles and Biomes
- Biome: A large geographic area with similar climates and ecosystems.
- Biosphere: The sum of all ecosystems on Earth.
- Carbon Cycle: The movement of carbon atoms through living and non-living components.
- Nitrogen Cycle: The movement of nitrogen through living and non-living components.
