Study Notes
Biotic and Abiotic Factors
- An ecosystem is shaped by both living (biotic) and non-living (abiotic) factors
- Species and physical conditions interact, creating diverse environments
- Interdependence of organisms in an ecosystem often results in approximate stability over a long time
- Populations can fluctuate depending on environmental factors or other species
Defining Ecosystem
- An ecosystem is a defined area where living and non-living environment factors interact
Interconnectedness in Ecosystems
- Ecosystem members depend on each other for survival
- For example, plants depend on animals to release carbon dioxide, a vital component for photosynthesis
Biotic Factors
- Biotic factors are the living components of the environment
- These factors include all living things that affect an organism
- Examples: animals, trees, parasites, pathogens, seeds, fruits
Abiotic Factors
- Abiotic factors are the non-living components of the environment
- These include all non-living factors that affect an organism
- Examples: temperature, humidity, pH, salinity, oxygen concentration, sunlight, soil type, rainfall, climate, wind, precipitation, water, air, and rocks
Activity: Classification of Biotic and Abiotic Factors
- Activity involves categorizing various factors (frog, oak tree, water, sunlight, human, rocks, soil, fungus, air) into their respective categories of biotic and abiotic
