Answer 2

Answer:

Parasitism

Explanation:

Parasitism is the association of organisms wherein one of the organisms, the parasite, derives its nutrition or other resources from the host organism.  

In the given example, wasps inject their eggs into the caterpillar to allow their larva to derive nutrition from the caterpillar. Here, the wasps are benefitted while the caterpillars are harmed as their larva die of lack of nutrition. Hence, it is an example of parasitism.
