Answer:
Europe can be considered as a cultural region.
Explanation:
Europe is part of the Eurasian continent. It has been defined as a separate continent not as all others, but on the basis of culture, religion, and race. While this may come as strange, it is not actually, as almost all ethnic groups are descended from the Aryans, speak Indo-European languages, and follow the same religion (Christianity).
These traits put Europe on the map as a cultural region. Not to be confused though, as these are all general traits, which is in contrast with the high amount of different cultures, languages, and religious fractions throughout Europe. While the continent as a whole can be defined as a cultural region, it has to be mentioned that there are also smaller ethnic groups like the Magyars, Szekely, Finns, Basques, Tartars, etc. that come from different cultural, ethnic, and in some cases religious backgrounds.
Climate and their level of agricultural technology

Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
