The solutions, which have both hydrogen and hydroxide ions in equal number are neutral solution.
In a solution, if the hydrogen and the hydroxide ion are in equal number, they will mask each other's effect. So, all over, the effect of the hydrogen ion or hydroxide ion would be absent. So, the solution would indicate a pH of value 7.
Hence, the given blank can be filled with neutral.
Nearly all energy for life comes from the sun through processes like photosynthesis, which converts sunlight into chemical energy. Heterotrophs obtain their energy from the food they eat, which comes from plants or other animals that derive their energy from the sun.
Almost all energy for life comes directly or indirectly from the sun. Plants use photosynthesis to capture sunlight and convert it into chemical energy in the form of ATP. Heterotrophs, such as animals and humans, obtain their energy by consuming plant or animal matter, which ultimately derives its energy from the sun.
