Answer 2

 Nectar is a sugar-rich liquid produced by plants. It is produced either by the flowers, in which it attracts pollinating animals or by extra floral nectaries, which provide a nutrient source to animal mutualists providing anti-herbivore protection. It is produced in glands called nectaries. 
Nectar is an economically important item, the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of many predatory insects, as well as hummingbirds and butterflies, feed on nectar.
