Today Food Security is a widely- used common term and is often relating to Climate Change Effects. But it is a combination of many factors with the initial source of energy for all biological systems. In the process of photosynthesis, solar radiation energy is transformed into chemical energy; the later is then converted to mechanical and thermal energy through metabolism. Herbivorous obtains necessary energy by digesting plant tissue and reserves, while flesh-eating organisms digest animal food, through a number of links, called “food chain” which may be up to five and then the energy flow gradually abates as it passes through the ecosystem . However, the primary producers, the plants take carbon dioxide and oxygen from the air, and the other nutrients from the soil, the overall source, except a few exceptions of some aquatic plants where they can obtain nutrients from dissolved water.
