Food spoilage is the undesired process through which the quality of food deteriorates to a point that it no longer remains fit for eating. Such a food becomes harmful or poisonous and any one eating such type of food may fall ill seriously.

Some leaves are very short, as short as they cannot be seen through naked eyes where as there are big broad leaves that can form many umbrellas for small children.

This energy runs the process of photosynthesis through which glucose is basically synthesized in leaves and green stems on combining together the atmospheric carbon dioxide and water.
Humans have a complex relationship with animals and use them for a variety of purposes. There are working animals, companion animals, animals used for scientific research, and animals used for food and by-products.

Animals could be mainly divided into wild and domestic. However, the domestic animals that live under wild conditions are called Feral Animals.
