Behavior Chain
Quick answer
A sequence of individual trained behaviors linked together so that completing one becomes the cue for the next.

What it means
In a behavior chain, only the very first step is triggered by an external cue from the handler, everything after that is prompted by the completion of the previous step in the sequence, with the reward typically arriving only at the end. Chains are usually built backward, teaching the last step first, so that each newly added earlier step is reliably followed by an already-fluent, well-rewarded piece of the sequence.
A real example
A dog trained to fetch a specific toy, carry it to its owner, and drop it in a basket has learned a behavior chain, each piece (grab, carry, release) cues the next, with one cue ("clean up") starting the whole sequence.
Common mistake
Trying to build a chain start-to-finish in the order it will eventually be performed, rather than backward from the last step, which usually falls apart because the earlier steps aren't yet reliably followed by something rewarding.
