Answer:
The main inter-specific population regulatory interactions are:
- Predator-prey relationship
- Mutualism
- Commensalism
Predator-prey relationship:
Predators can actually make the population of a prey stable by feeding on organisms which are weak or old in a prey population.
Mutualism:
Mutualism can be described as a type of interaction in which both organisms benefit from each other.
Commensalism:
Commensalism is a type of interaction in which one organism benefits from the other organism while the other organism neither gains benefit nor is harmed.
