When the environment is no longer suitable for the organism due to less food, climate change, etc, the population will change.

point mutations, errors in gene coding when transmitting between generations, change in environment, radiation
basically a population is suited to its environment, but there is small variation in the group... if the environment they are in changes, and the things that help them to survive are now different, then those with the ability to survive better will survive longer and reproduce more, thus their genes will come to make up more of the population

A change in competion for food, a change in the food available, a change in predatory species which kill the organism, a change in the environment.
