The activation energy of a given chemical reaction is the minimum required amount of energy needed to start the reaction, for the reaction to start. All reactions have an activation energy, even spontaneous ones, ones that do occur spontaneously. It is a thermodynamic barrier that separates the amount of energy reactant molecules must possess to ultimately react with each other to produce the respective products.
The more plants and animals in a habitat, the greater the biomass, which is now habitats store energy. The greater the number of species the more competition there is for food between predators, which sustains their populations
