To study biodiversity, a group of students are taken to a zoo and another to a safari in the woods. Which is the better way of learning and why? What more can you gain from such experiences?

For studying biodiversity, safari in the woods is a better way as compared to a zoo. This is because
(i) Both animals and plants are found in woods while zoo
contains only captured or endangered animals in an artificial habitat, cared by humans.
(ii) The life forms are much more in woods than in zoo, thus providing a wider aspect of biodiversity.
Gain from such experiences Importance of living organisms and self-realisation of how our activities are affecting the biodiversity negatively.
