These two closely related species have evolved to use the resources of an ecosystem in a different way, in order to be able to cohabit and coexist. Niche is an ecological term used to refer to the ecological roles of species in an ecosystem. In the same context, niche differentiation refers to the process by which competing species use the environment differently in a way that helps them to coexist. In addition, interspecific competition is another ecological term used to describe how individuals of different species compete for the same resources in an ecosystem. When individuals of these two species of swallows live on the same ecosystem, they compete against the resources (food and habitat) that are available in this habitat. Due to niche differentiation, they are able to coexist in the same ecosystem by limiting their habitat.
Animals can be either warm-blooded or cold-blooded. Warm-blooded animals, which are mostly birds and mammals, need to maintain a relatively constant body temperature or they would suffer dire consequences. It doesn't matter what the outside temperature is—they must maintain the same internal temperature.

I believe heterotrophs are organisms that get their energy by eating other organisms. These organisms are also called predators
