Final answer:
The relationship between crocodiles and Egyptian plovers is called mutualism.
Step-by-step explanation:
The relationship between crocodiles and Egyptian plovers is called mutualism.
Mutualism is a type of symbiotic relationship where both species benefit from their interaction. In this case, the crocodiles benefit from the plovers because the plovers eat parasites, insects, and dead skin off the crocodiles' hides, providing a cleaning service. The plovers benefit by getting a meal and a safe place to perch on the crocodiles' backs, as the crocodiles do not eat the plovers.
This mutually beneficial relationship helps both species survive and thrive in their ecosystem.
