It requires a higher level of engagement and interaction among participants. On the other hand, cooperation is more about individuals or groups working alongside each other, each contributing their efforts towards a shared objective without necessarily sharing the same level of involvement or decision-making. Cooperation may involve less direct interaction and coordination compared to collaboration. **
