What is a habitat?
The place where an organism lives
What is a population?
All the organisms of one species living in a habitat
What is interdependance?
When other species rely on each other
What is a community
The populations of different species living in a habitat
What is an ecosystem?
The interaction of a community of living organisms (biotic) with the non-living (abiotic) parts of their environment.
Examples of biotic factors?
• New predators • New pathogens • Decrease in food (animals)
Examples of abiotic factors?
• Light intensity • Temperature • Moisture levels • Soil pH and minerals • Wind intensity and direction • CO2 levels for plants • O2 levels for aquatic animals
What is a stable community?
• All species and environmental factors are in balance • Number of species remain relatively constant • Population sizes remain relatively constant • Established over many years • Often have a high biodiversity • Can absorb some change • Cannot easily be replaced
