Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.
If the temp.rises then it will lead to excessive evaporation in hydrosphere, on lithosphere it willl cause extreme hot conditions and with the scarcity of water the animals, birds will die and also plants will be affected.Hydrosphere and lithosphere are included in biosphere so it willl altogether effect biosphere...
