Health and nutrition are closely linked in a malnutrition-infection cycle in which diseases contribute to malnutrition, and malnutrition makes an individual more susceptible to disease. Malnutrition is the result of inadequate dietary intake, disease or both. Disease contributes through loss of appetite, malabsorption of nutrients, loss of nutrients through diarrhoea or vomiting. If the body's metabolism is altered the greater the risk is of malnutrition.
âThey studied giant redwoods, the tallest trees on earth in Humboldt County California to reach these conclusions. They hypothesized and verified experimentally that as trees reached the height of 425 they could pump less and less water and nutrients up to new growth at that level. No current tree in the world has reached this height.
Eucalyptus is one of three similar genera that are commonly referred to as  eucalypts , the others being Corymbia and Angophora.everal eucalypt species are among the tallest trees in the world. Eucalyptus regnans, the Australian 'mountain ash', is the tallest of all flowering plants (angiosperms); today, the tallest measured specimen named Centurion is 99.6 m (327 ft) tall.
