Oxygen is the product of photosynthesis. Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide gas and water in the presence of sunlight. Glucose is stored in different parts of plant body and oxygen is released in the atmosphere which is used by living organisms. Carbondioxide is taken by the plants from the atmosphere through stomata and water is absorbed by the plant from the soil through roots.
Biomes are typically not classified by temperature, because some biomes can experience extreme temperatures from one season to the next. Other biomes might have a more consistent temperature throughout the year.
