Explanation:

Competition is a negative ecological interaction between the members of two species. Here, two species compete for one or more resources. Competition mostly occurs for food. However, species also compete for other resources. Since both the competing species are negatively affected by this interaction, competition is said to be "-/-" interaction. Both lions and hyenas are carnivores and compete for the prey species such as porcupines, hares, zebra, etc. Therefore, their interaction is represented as “-/-“.
