The variability of life forms on earth constitutes the biodiversity. All forms of life on earth including plants sp, animals, micro organisms, the genes they contain and the ecosystem they form make up biodiversity.
These are categorized into three namely; genetic (variation that exist within species), species (the total number of species in a defined area) and ecosystem (variety of habitats, biotic communities and ecological processes) biodiversity.
Biodiversity; refers to the variety and variability of life on earth. It consist of the varieties all forms of life on earth including the different plants, animals, micro organisms, the genes they contain and the ecosystem they form.

Levels of Biodiversity
These consist of genetic, species and ecosystem biodiversities.
1. Genetic diversity: it is the gene variation that exist within species and populations of plants, animals and micro organisms
2. Species diversity: this refers to the total number of species in a defined area. Mangalet and menhink are some of the indices used in the measurement of species diversity.
3. Ecosystem diversity: this refers to the variety of habitats, biotic communities and ecological processes taking place in the biosphere.

Biodiversity can be said to be all life forms on earth whether plants sp, animals, micro organisms and all that make up the ecosystem.
All forms of life on earth including plants sp, animals, micro organisms, the genes they contain and the ecosystem they form make up biodiversity. They exist in three levels namely; genetic, species and the ecosystem.
