Answer:
mutualism
Explanation:
Mutualism is a type of ecological interaction between two species in which both have benefits (double positive interaction). Mutualism also can be considered as a type of symbiosis-two species that live together. Termites and protozoans are a great example of correlation between two species that work together and provide positive effect one to another. Termites provide food to protozoans, while protozoans provide energy to the termites.
