seasons in each year that resources and the environment aren’t friendly or
rather callous with living organisms, climates that include winter, most
especially. Or natural disasters like storms, hurricanes, earthquakes and tidal
waves that prohibit living organism to limit its food intake and due to
scarcity.
2. Obtaining the
resource or food. It may be very rare or in certain occasion only for the
organism to acquire such exquisite resource to become its food.
