What is an example of interdependence
Clown fish and anenome:
- clown fish is protected and has a habitat in the anenome
- clown fish removes parasites off the anenome
——> therefore it is a mutualistic relationship because the anenome and clownfish benefit from each other
What is interdependence
The dependence of all living organisms on each other within the community for different things
What is a stable community
- environmental factors and numbers of different species is relatively constant. It they are changing they are changing in cycles such as with the seasons of the year

- mates
What is intraspecific competition
Competition within the same species
What is interspecific competition
Competition between different members of different species
What do plants compete over
- light
- space
- water
- mineral ions (nutrients)
What are Abiotic factors
Non living factors of environment e.g. temp
What are biotic factors
Living factors of the environment e.g. food
What do animals compete over
- territory
- food
- water
- mates
Give examples of Abiotic factors
- Moisture levels
- Light intensity
- Temp
- CO2 levels
- Wind intensity and direction
- Oxygen levels
- Soil pH and mineral content
