Study Notes
Ecology
- The study of how living things interact with each other and their surroundings.
The Environment
- All factors affecting an organism.
- Consists of living (biotic) and non-living (abiotic) factors.
Abiotic Factors
- Intensity of light
- Temperature range
- Moisture levels
- Type of soil or rock
- Mineral availability
- Supply of gases like oxygen, carbon dioxide, and nitrogen
- pH
Limiting Factors
- Abiotic factors can vary within the environment.
- These variations can act as limiting factors, determining which organisms can thrive in a specific environment.
Habitat
- The place where an organism lives.
- An organism's habitat meets its needs, including food, water, and shelter.
Different Land Habitats
- Desert
- Tundra
- Grasslands
- Forest
- Rainforest
Ecosystem
- The interconnected relationships between organisms and their environment.
Biosphere
- The portion of Earth where life exists.
- Composed of numerous complex ecosystems.
- Includes interactions between abiotic (physical) and biotic (living) factors.
- Members of the community and the environment must interact to maintain balance.
Symbiosis
- The act of living together, either temporarily or long-term.
- At least one organism benefits from the relationship.
Types of Adaptations
- Increase chances of survival and reproduction.
