The biosphere (which is technically a spherical shell) is virtually a closed system with regard to matter,[1]with minimal inputs and outputs. Regarding energy, it is an open system, with photosynthesiscapturing solar energyat a rate of around 100 terawatts.[2] By the most general biophysiologicaldefinition, the biosphere is the global ...
Biodiversity (or biological diversity) is the variety and variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. [ 1 ] Diversity is not distributed evenly on Earth.
