Hint: The certain species of animals are getting endangered due to human activities like hunting and poaching and also due to natural calamities. There is a need to protect these species from getting extinct. Several national parks and biosphere reserves are set up to protect the animals in their natural habitat.
To solve this question, we must know about the natural habitats being set up to protect the animal.
Wild life sanctuary is a place where animals can live their life in protected areas in their natural habitat. It helps in protecting the animal from illegal activities and also helps the endangered animal breed and protect them from extinction.
Zoo-It is a place where animals are kept for public display. They are not kept in a natural habitat rather they are kept in cages for recreational purposes.
Aviary-Aviary is a place where birds are kept in confined spaces where they can fly.
Park- A Park is an area of semi-natural or manmade space which is set for human recreation or for protection of wildlife.
