Hyenas and lions have fierce battles over food. which type of relationship does this describe?

Competition

Organisms compete for the resources they need to survive in an ecosystem such as air, water, food, and space. Competition both within and between species is an important topic in ecology. Every individual in an ecosystem requires certain things to survive and to reproduce. They compete with members of their own species (intra specific) and members of other species that need the same things (inter specific). The most important of them is food so the relationship between hyenas and lions over food is called a competition in the given ecosystem.
