The follow-up program on convention on biological diversity i.e. World summit on sustainable development was held at Johannesburg in 2002.

There is more solar energy available in the tropics. This contributes to biological diversity. Also, rainfall is high in the tropics. This also favors biodiversity.

River popper hypothesis explains the effect of extinction on the function and diversity of ecological community. It says every species is important for the performance of the ecosystem and extinction of a species may pose a serious threat to the ecosystem.

Biodiversity is directly used as a source for food, fibre, fuel and other extractable resources. The social value of biodiversity includes aesthetic, recreational, cultural and spiritual values. To this can be added health benefits resulting from recreational and other activities.
The extinction of species is not considered as the benefit received from biodiversity.

Ecological diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity.

Percentage of energy that can be transferred from one trophic level to another is 10%. This is in accordance to the ten percent law.
The Ten percent law of transfer of energy from one trophic level to the next was introduced by Raymond Lindeman (1942). According to this law, during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the energy from organic matter is stored as flesh.

Clover is a producer, grasshoper is a herbivore, rat is a primary consumer and hawk is a secondary consumer.
