Explanation:

1. In a community, the three main types of relationships are predator - prey, competition (where organisms compete for resources like food, water, or space), and symbiosis (close and long - term interactions between different species).
2. When members of populations work together for survival, it is a cooperative relationship.
3. A close relationship between two species involving energy exchange is symbiosis.
4. For mutualism, the definition is “a symbiotic relationship in which both species benefit”.
