Ecological functions- Forests play important role for natural factors like climate, carbon storage, nutrient conservation etc. In winter, on the other hand, forests ensure that the heat emitted by the ground is not lost. Charles Darwin, famous for his Theory of Evolution, came up with a metaphor he called the "tree of life". On the other hand, Net Productivity is the amount of remaining biomass present in plants or producers which becomes the food for herbivores. Forests aren't only trees, however. However, fluctuation in the temperature is quite reasonable. In the northern middle Himalayas trees like oak, maple, rhododendron, ferns are found.

These forests shed leaves in each fall and develops in each spring, with a decrease in latitude more evergreen broadleaf trees appear. They return nutrients to the soil, continuing the natural cycle. Tropical forests represent < 15% of Earth's terrestrial surface yet support > 50% of the planet's species and play a disproportionately large role in determining climate due to the vast amounts of carbon they store and exchange with the atmosphere.
