Surface tension allows organisms to walk on water, like certain insects do, by supporting their weight. It also helps organisms trap and feed on prey by creating sticky surfaces, like on the tentacles of some aquatic animals. Additionally, surface tension can assist in regulating water loss in organisms that live in arid environments.
Organisms in the aphotic zone rely on detritus, organic matter sinking from the surface, and chemosynthesis, where bacteria and other organisms use chemical compounds to produce energy. Some organisms may also migrate to the surface at night to feed on organisms that have photosynthesized during the day.
This element is oxygen.

Dark regions on the surface of the moon are generally basalt flows. Basalt is a dark rock. The flows have been caused by rock melting due to heat generated by meteor impacts.
The official definition of the word biosphere is the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
Organisms can exist on the surface of the earth in the biosphere, which includes all regions of land, water, and air where living organisms are found. The biosphere is where plants, animals, and other life forms interact with each other and with their physical environment.
Different organisms are distributed unevenly across Earth's surface due to variations in climate, habitat availability, and resources. For example, tropical regions have high biodiversity due to the warm, moist conditions, while polar regions have lower biodiversity due to extreme cold. Organisms are also influenced by human activities, such as deforestation and urbanization, which can alter natural distribution patterns.
Approximately 29% of the Earth's surface is occupied by the continents and islands. The remaining 71% is covered by oceans.
0.0002%
The portion of Earth's surface occupied by permanent human settlement.
Plains regions cover about 55% of the Earth's land surface.

It's the biosphere. It supports living things and humans.
The biosphere, which includes the surface of the Earth, is capable of supporting life. This area includes regions such as oceans, forests, deserts, and other ecosystems where living organisms can thrive.
Organisms that are permanently attached to a surface, instead of being able to move freely, are called sessile. Plants, mussels and barnacles are examples of sessile organisms.
An epithelial cell can be divided into two functional regions: the apical surface, which faces the external environment or a body cavity, and the basolateral surface, which interacts with neighboring cells and the extracellular matrix. These regions are important for different functions such as absorption, secretion, and cell-cell communication.
