Therefore, the only activity that is almost practiced exclusively in rural area is agriculture. Urban areas don't have much space and well environment for agriculture activities.
Agriculture activities can be energy consuming as some may require different machines to help with farming processes such as harvesting or irrigation.
The electrons are used to generate ATP and its equivalent forms.
Answer: The deep-sea organisms found today have undergone evolution in the past and are very complex now because their body structure also varies from that of the organisms that are present at a lower depth.
The bodies of these organism does not contain any air cavities in which the pressure could exert. It is because of this, the organism are quite solid without any air in their bodies, thereby they can withstand extreme high pressure.
