The same ligand can bind to different receptors causing different responses (e.g.. acetylcholine). On the other hand, different ligands binding to different receptors can produce the same cellular response (e.g. glucagon, epinephrine).
In paracrine signaling the signaling molecule affects only target cells in the proximity of the signaling cell. ... Once a signaling molecule binds to its receptor it causes a conformational change in it that results in a cellular response. The same ligand can bind to different receptors causing different responses.
One consequence would be that population would make it so their would be less food for them and then any species under that would be endangered eventually
