Biology, Ecology, Metabiology

One standard definition of 'Ecology' is 'the study of the relations between an organism and its environment'.  However, since Ecology does not typically pertain to the relations between an organism and one component of its environment--other organisms of the same species--'the study of the relations between a species and its environment' seems to be a more accurate characterization.  Similarly, while 'Biology' is typically conceived as 'the study of the life-processes of an organism', some of those processes are reproductive, and, thus, pertain to its species, thereby suggesting an analogous modification of that definition to 'the study of the life-processes of a species'.  However, insofar as those internal processes are systematically related to external relations, e. g. chemical exchanges, there seems to be no sharp distinction between Biology and Ecology.  Instead, the interaction of the two fields suggests that they are branches of an overarching one, that can be called 'Metabiology'.
