What is calle when something occurs when organisms fight for limited resources?

When organisms compete for limited resources, it is referred to as "intraspecific competition" if it occurs within the same species, or "interspecific competition" if it happens between different species. This competition can involve resources such as food, water, space, or mates, and it plays a crucial role in natural selection and ecological dynamics. The outcome of this competition can affect population sizes and the distribution of species within an ecosystem.
