Relationships between the elements of a system
Relationships between elements can be described as flows:
▪ Flow of materials, and
▪ Flow of information
There are two types of interaction exists in the system:
1. Positive feedback loops: A larger population leads to more births occurring (the larger the number of people in the population, the more babies are born)
2. Negative feedback loops: A system with negative feedback tries to stabilize itself according to the rules: the larger something is – the smaller something becomes. For example - if there is a limited food supply and the population grows – the less food per person)
