Illustrate the hierarchical classification of life by giving the scientific names of its species, genus, family, order, class, phylum, and kingdom. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. All of these bio-products are potentially renewable resources that can be harvested and managed on a sustainable basis (see Chapter 12). Scientists have found between 1 and 2 million different species. World Atlas of Biodiversity: Earths Living Resources in the 21st Century.

Biodiversity is the number and variety of plants, animals and other organisms that are living in an ecosystem. Similarity is judged using information about anatomy, development, biochemistry, behaviour, and habitat selection. Is the human existence somehow impoverished by extinctions caused by our actions? Species are a familiar element of biodiversity.
