Recharge of aquifers or groundwater sources mainly occurs through infiltration of precipitation, where water from rain or melting snow seeps into the ground. This process replenishes the groundwater supply by filling up the pore spaces in soil and rock layers. Other sources of recharge may include surface water bodies, such as rivers or lakes, that contribute to groundwater through seepage or infiltration.
A plant gets its food mainly from sunlight, and good soil in the ground. They can also suck up water from the ground with their roots.
Coal
To the best of my knowledge, the water under the surface was formed when the oceans were formed, or thereafter. In simple terms, cracks in the ground allows water to leak below ground into large open voids.
Mainly because there is no sunlight available in the ground and the seed has no chlorophyll to use the sunlight.
Ground substance is located within the extracellular matrix of connective tissue. It fills the space between cells and fibers and provides support, lubrication, and a pathway for nutrient exchange. Ground substance is mainly composed of water, proteoglycans, glycoproteins, and other molecules.
San Antonio primarily sources its water from the Edwards Aquifer, a significant underground water reservoir, along with surface water from the San Antonio River and several local lakes. Austin's water supply comes mainly from the Colorado River, supplemented by groundwater from the Edwards Aquifer and other smaller aquifers. Both cities implement conservation measures to manage their water resources effectively.
Mainly the Oceans.
Energy comes mainly from sources such as fossil fuels (coal, oil, natural gas), renewable sources (solar, wind, hydroelectric), and nuclear power. These sources are used to generate electricity and power vehicles, homes, and industries.
Aquifers primarily purify water by filtering out impurities through the natural layers of soil and rock that the water passes through as it percolates down into the aquifer. This process helps to remove contaminants and improve the quality of the water stored within the aquifer.
No, it's a vegetable, so it consists mainly of carbohydrates. Protein comes mainly from animal sources and legumes.

Guatemala mainly uses its oil reserves.

Mainly coal and oil, but also natural gas.
Mainly to translate C sources into objects modules.
In general, sites that are free to access cover their expenses from other sources - and these other sources are, usually, mainly advertising.
