What is biodiversity? Why is biodiversity important for human lives?

Correct Answer

Biodiversity or Biological Diversity refers to the immensely rich wildlife and cultivated species that are diverse in form and function but closely integrated in a system through multiple networks of interdependencies.

It is important for human lives because we form a complex web of ecological system and are dependent on it for our existence. Plants, animals, and micro-organisms re-create the quality of air, water, and soil that produce our food, without which we cannot survive. Additionally, biodiversity preserves genetic diversity for better growth of species and breeding, which supports agriculture and fisheries.

Explanation

The answer is derived directly from the textbook definitions and explanations provided in the context. The first paragraph defines biodiversity as described in the section 'Flora and Fauna in India'. The second paragraph explains its importance by referencing the 'ecological system' dependency mentioned in the first chunk and the 'life support systems' (air, water, soil) and 'genetic diversity' mentioned in the 'Conservation of Forest and Wildlife in India' section.

Solution Steps

  1. Step 1: Define Biodiversity using the text: 'immensely rich in wildlife and cultivated species... closely integrated in a system through multiple network of interdependencies.'

  2. Step 2: Explain importance using the 'web of ecological system' concept and human dependence on air, water, and soil.

  3. Step 3: Include the point about genetic diversity and its role in agriculture and fisheries to ensure a comprehensive 3-mark answer.
