List at least three factors that would cause an organism to migrate one habitat to another

1. Escaping a predator - this increases its chances of survival. It could move to an area with low predator population

2. Finding food - food might get scarce in the current habitat and hence increased competition in the community. Finding another habitat with a higher availability food will increase survival

3. To find a mate / to reproduce - reproduction in an intrinsic compulsion in all animals as a means to perpetuate their own gene. Solitary animals, such as the leopard, leave their habitat to find a mate and reproduce.
