    Scope of studying Biology

    Scope of studying Biology

    Biology creates an awareness of a vast array of forms of life. It offers a large scope and provides a large field of study.

    • Biology and inter-relationship of living beings: Study of biological processes helps us in understanding the wonderful phenomenon and laws of nature which finally tell us to predict the behaviour of different living organisms under changed conditions.

    • Biology and resources: Study of biology helps us to know how to tap and conserve the resources available to us. For example: Fishes, Birds, Forests, etc.

    • Study of nature in rewarding experience: Various plants like Narcissus, Dahlia, Gloriosa, Roses, Marigold, Aster,etc are used for ornamental purposes. The variety available in animals is broadly enjoyed in zoological parks. Students enjoy wandering to remote places watching never seen before plants and animals.
