Study Notes
Abiotic Factors
- Non-living components of an ecosystem including temperature, water, sunlight, wind, rocks, and soil.
Biotic Factors
- Consist of living organisms within an ecosystem, such as plants, animals, fungi, and bacteria.
Levels of Organization
- Organized in a hierarchy:
- Organism
- Population
- Community
- Ecosystem
- Biosphere
Prefixes
- "Bio": Relates to life or living entities.
- "A-": Indicates absence or negation (not or without).
Carrying Capacity
- Represents the maximum number of individuals in a population that an environment can sustain without degrading.
Limiting Factors
- Environmental conditions that restrict where organisms can survive and thrive.
Biotic Limiting Factors
- Include:
- Competition for food
- Predator-prey dynamics
- Parasitism
- Disease spread
Abiotic Limiting Factors
- Include:
- Sunlight availability
- Water supply
- Ambient temperature
- Availability of living space
Impact of Biotic Populations on Abiotic Factors
- An increase in biotic populations can lead to scarcity of abiotic resources due to heightened demand.
Competition for Abiotic Factors
- Organisms vie for essential resources such as food, water, sunlight, and living space crucial for survival.
Competition in Forest Ecosystems
- Example competitors:
- Tapir and Deer, which compete for various plant species as a food source.
Survival in Desert Ecosystems
- Example biotic factors:
- Desert Foxes and Armadillo Lizards depend on limited water resources and shelter for survival in arid conditions.
