Study Notes
Ecosystem and Community
- An ecosystem is a group of living and nonliving things in an area interacting.
- A community is two or more species in the same area at the same time.
- A population is a group of the same species in an area.
Factors in an Ecosystem
- Biotic factors: Living things in an ecosystem.
- Abiotic factors: Nonliving components of an ecosystem.
Species and Habitat
- A species is a group of organisms similar enough to reproduce together.
- Habitats are the homes of animals.
Predator and Prey
- Prey: Food source for other animals.
- Predators: Animals that hunt prey.
Energy and Energy Sources
- Energy producers: Coal, Solar, Hydropower, Wind, Nuclear Power.
Methods of Heat Transfer
- Conduction: Direct contact, where faster-vibrating molecules transfer energy to slower ones.
- Convection: Heat transfer in liquids or gases due to temperature differences.
- Radiation: Heat transfer through electromagnetic waves.
Insulators and Conductors
- Insulators: Materials that trap heat.
- Conductors: Materials that allow heat transfer.
Natural Energy Sources
- Hydropower: Energy from water.
- Geothermal: Energy from the earth.
- Solar: Energy from the sun.
- Wind: Energy from wind.
Advantages and Disadvantages of Natural Energy Resources
- Advantages: Renewable, less pollution.
- Disadvantages: May be location-specific, with high initial costs.
- Impact on Environment: Reduced carbon emissions.
- Impact on Lifestyles: More sustainable living.
- Impact on Health: Cleaner air and water.
