A food chain can change in a number of different ways, but ultimately, it is because a member of that food chain is removed, or a new member is added into the food chain.
For instance, if we have a hypothetical food chain in which the banana tree produces bananas, which are eaten by monkeys, which are in turn eaten by hawks. If the banana stops producing bananas (due to environmental reasons), thus the banana tree is removed from the food chain and the monkeys will have nothing to eat. The monkeys will die out, and soon the hawks will have nothing to eat as well.
Another example would be if eagles were introduced into the food chain. Due to a migratory change, eagles find themselves in the same place as our hypothetical food chain, and begin competing with the hawks for food. Because they both eat monkeys, sooner or later, the monkey population will be hunted to the point of extinction. Because of that, both eagles and hawks will end up starving once the monkey population is gone.

Why are long food chains less effective in transferring energy than short food chains?
Short food chains are more efficient than long food chains because you lose energy as you go up the chain. For example, if we say that plants take in 100% of the possible energy, when a rabbit eats that grass, the rabbit only gets 50% of the energy because the plants were using their stored energy to make food. It continues on like this for as long as the food chain lasts. (Note: the amount of energy isn't correct; I just used those percentages as examples.
