Habitat

noun (countable)
/ˈhæb.ɪ.tæt/
The natural environment in which an organism or ecological community lives and which supplies the physical, chemical, and biological resources (food, water, shelter, breeding sites) necessary for survival and reproduction. Habitat is distinct from niche (the functional role of an organism) — an organism's niche is what it does; its habitat is where it lives. In Indian wildlife law, critical habitat is a notified area under the Wildlife (Protection) Act, 1972 (as amended 2006), conferring the highest level of protection within a Tiger Reserve's core zone.

✍️ Usage in a UPSC answer

🔡 Root

Latin habitare = to dwell, inhabit; third person singular present: habitat = 'it dwells'

📜 Etymology

Directly borrowed from Latin habitat ('it inhabits/dwells'), third-person singular present of habitare, frequentative of habēre (to have, to hold). The term was introduced into natural history literature by botanists as a standard tag in flora descriptions from the late 18th century, replacing longer Latin descriptive phrases.

🧠 Memory Hook

HABITAT = HABIT + AT. An animal's habitat is simply the place it has the habit of living at. The Latin root habitare (to dwell) is also the root of habit — where you repeatedly live becomes your habitat.
