Study Notes
Key Ecology Definitions
- Habitat: The place where an organism lives.
- Population: All organisms of the same species in a habitat.
- Community: All the populations of different species in a habitat.
- Abiotic Factors: Non-living parts of the environment.
- Biotic Factors: Living parts of the environment.
- Ecosystem: The interaction of a community of biotic organisms with their abiotic features.
Competition
- Organisms compete for resources to survive.
- Plants need light, water, and space to grow.
- Animals need space, food, water, and mates to reproduce.
Biotic and Abiotic Factors
- Biotic factors: Predators, prey, competition for resources, and diseases.
- Abiotic factors: Light intensity, temperature, carbon dioxide, oxygen, and moisture levels.
Adaptations
- Behavioral adaptations: The way an organism behaves, such as birds migrating.
- Structural adaptations: Features of an organism's body structure, such as whales having blubber for warmth.
- Functional adaptations: Functions within an organism, such as bears hibernating to slow their metabolism.
Food Chains
- Food chains show the transfer of biomass between trophic levels.
- Producers are the first trophic level with 100% biomass.
- Biomass is lost during each transfer due to digestion and other processes.
- The predator-prey cycle shows the relationship between predator and prey populations over time.
Water Cycle
- The water cycle is a continuous process of evaporation, condensation, and precipitation.
- Water evaporates from bodies of water and plants, condenses into clouds, and precipitates back to Earth.
Carbon Cycle
- The carbon cycle involves the exchange of carbon between living organisms and the environment.
- Photosynthesis and respiration are crucial processes in the carbon cycle.
- Carbon is stored in plants, animals, soil, and fossil fuels.
- Burning fossil fuels releases carbon dioxide into the atmosphere.
Biodiversity
- Biodiversity is the variety of different species of organisms.
- High biodiversity is essential for stable ecosystems.
- Human activities like waste production, deforestation, and global warming negatively impact biodiversity.
