Answer:
Gnawing and chewing of plants.
Explanation:
Diastema are spaces found in the dentition of most mammals or any organism that has teeth. It is a space separating dentition for different functions, specially that amongst the biting tooth and grinding tooth. Rabbits are been used as a case study because they are herbivores and also don't have canines, so the diastema helps with gnawing and chewing of plants.
It is well known according to study that a great number of herbivores have no canine, so the diastema aids in holding, gnawing and chewing of plants. This is really helpful, considering rabbits are herbivores.
