Sunlight ( the source of energy), air (composed mainly of oxygen and carbon dioxide), water, food (nutrients), temperature (a habitat with a right temperature for different kind of organisms).
Cells make up the smallest bits of every living thing. Everything that contributes to a living thing being alive comes from cells, making it the fundamental part of life.
In order to reduce the activation energy in a chemical reaction. a catalyst is introduced to lower the activation energy of a reaction, so that a chemical reaction can take place. However, by increasing the temperature of a reaction helps the effect in increasing the number of reactant particles that have more energy than the activation energy. Therefore, by reducing the activation energy, the reaction would go faster.
