adapted animals

Background

There is a great diversity in the animal world. Amongst the land animals some are adapted to cold climate, some to hot climate (for example, hilly areas, plains, deserts) while some are adapted to wider environmental conditions. These animals adapt themselves in different ways to the climatic conditions of the place where they live. A variety of animals brought from different habitats are kept in zoological gardens or zoos. These animals are maintained for exhibition, education and research. Efforts are made to provide these animals conditions similar to their natural habitat.

Methodology

1. Visit a zoo near your area.

2. Note down the names of as many animals as possible from different climatic zones. Select any three animals for your study.

3. Find out which state or country the animal originally belonged to. You can do so from the information provided outside the enclosures of animals.

4. Find out the type of climate of the place where the animal belongs to.

5. Try to find out from zoo officials, caretakers and guides what special conditions are provided for a particular animal. You may enquire about conditions like food, temperature, humidity, surroundings, moving space, etc.

6. Also find out to what extent this artificial habitat affects their lives in terms of longevity, growth, health and reproduction.

7. Collect photographs/pictures of selected animals, if available.

Conclusion

Prepare a report showing how artificial environment has influenced the life of animals.

Follow-up

1. Find out the ways in which animals that you have listed adapt themselves to the climatic condition of the place.

2. Discuss in your class whether it is a good idea to keep animals in a zoo.
