There are any number of relationships, which transcend species lines, that are nonetheless vital for the proper functioning of the individual organisms within that biological relational field. These groups of organisms, or sometimes specific processes within these organisms, can form obligate (necessary) bonds that have the same characteristics as the relationships between the collection of vital organs in a singular body.
The relationships that define the integrity and continuing function of any single organism extends far beyond that singular organism’s membrane. Each organism exists by way of an extended network of mutually nourishing and defensive relationships that collectively nourish and defend the integrity of that community. This relational lens is far more useful to see the foundational principles of biology than is a reductionist, organism-centric lens.
The same community principle is what defines the strength and integrity of any complex adaptive system from a single cell, to organ, to the larger relationship economy we see expressed through ecosystems is also true of interpersonal relationships, families, groups, society and civilization itself. This is the underlying message communicated through the processes that define the biological economy – that forging mutualistic nourishing bonds, and by extension, a common defense, defines the level of adaptation any complex adaptive system will have to negotiate the environment.
Here is an example of one such inter-species relational bond that illustrates the type of bond that nourishes and protects a body of life, the same way organs in a multicellular creature relate to each other:
