What factors determine whether a species can be present in a place

The question is asking "what factors determine whether a species can be present in a place" and some factor that can affect whether species are, or not, present in a place are: the resources (what the species eats), predators (whether the species are threatened by other species), climate (whether it's warm or cold enough for the individuals of the species) and the possible competitor species

Sorry i don’t know the answer myself

Basically create a schedule on what you need to study and stick with it
