A satellite can focus on specific latitudes using oblique orbits.
The energy content of all food molecules can be traced back to the Sun. It is the process of photosynthesis that locks the Sun's energy into simple carbohydrates like glucose.
I believe that opiates tend to relieve pain. Opiates are drugs used to treat pain derived from the opium plant. They are highly addictive, so they pose the threat of opiate addiction (including opioid addiction) to any person who takes the drug for a prolonged period of time. They also include illegal drugs such as heroin, synthetic opioids such as fentanyl, and pain relievers available legally by prescription, morphine and codeine among others
A. the products of photosynthesis serve as the reactants and cellular respiration to provide chemical energy.
Because photosynthesis produces oxygen and cellular respiration needs that oxygen to produce energy and carbon dioxide, the carbon dioxide is used to create energy and oxygen for the plant.
