The conditions of a habitat remain changing abruptly and periodically. Abrupt changes in environment often do not give time to an organism to get ready and to face the challenges. As such the organism can survive only when it has sufficient abilities to tolerate these changes.
Many squirrels had made nests in upper portions of offices by depositing huge balls of wool like materials between the rows of files and old registers. Many times and many men spotted some or the other squirrel coming to the rows of files and registers placed there since many-many years.

Ecosystems can be categorised into two broad categories: natural and artificial. Natural Ecosystems are those ecosystems that operate by themselves under natural conditions. These ecosystems are further categorized as Terrestrial and Aquatic Ecosystems. Terrestrial ecosystems relate to lands, whereas Aquatic ecosystems relate to fresh or marine water. Freshwater ecosystems may be Lotic or Lentic. Lotic are running water ecosystems like springs, streams or rivers, whereas Lentic Fresh Water Ecosystems may be found in standing waters of lakes, ponds, pools, puddles, ditches, swamps, etc. Marine Ecosystems are found in marine waters of salt lakes, seas, oceans and estuaries. Artificial Ecosystems are man-engineered ecosystems like crop fields, artificial ponds and lakes, aquaria, fish ponds, and abandoned mines reclaimed as lakes or water bodies for recreation.

Continuous hunger weakens the immune system and makes them vulnerable to diseases and infections. Mothers who suffer continuous hunger often give birth to underweight and weak babies, and they face increased risk of death.
