The ultimate souce of energy for the food chain is solar energy from the sun. It allows plants to convert the solar energy to chemical energy for growth. The growing plants in turn allow heterotropic animals to consume them to obtain energy of their own.
Water obtained from water reclamation processes can be used for drinking, while greywater cannot.
Grey water refers to the collection of all the waste water that are generated in an household or in an office building minus the water used in the toilets or sewage system of those buildings. Generally, grey water contains few pathogens and it is easy to treat. Grey water are usually treated and then re-use for non potable uses such as flushing of toilets, irrigation, etc.
Water reclamation is the chemical process of recycling and converting waste water to water that can be re-used. The water can be used for different purposes depending on the level of treatment administered. Waste water can be treated to the extent that it can be used for drinking and other potable uses. This is the major difference between grey water and reclaimed water; while grey water can not be used for drinking and other potable used, reclaimed water can be used for drinking and cooking.
