Answer:

weed is a plant considered undesirable in a particular situation, "a plant in the wrong place". Examples commonly are plants unwanted in human-controlled settings, such as farm fields, gardens, lawns, and parks. Taxonomically, the term "weed" has no botanical significance, because a plant that is a weed in one context is not a weed when growing in a situation where it is in fact wanted, and where one species of plant is a valuable crop plant, another species in the same genus might be a serious weed, such as a wild bramble growing among cultivated loganberries. In the same way, volunteer crops (plants) are regarded as weeds in a subsequent crop. Many plants that people widely regard as weeds also are intentionally grown in gardens and other cultivated settings, in which case they are sometimes called beneficial weeds. The term weed also is applied to any plant that grows or reproduces aggressively, or is invasive outside its native habitat.[1] More broadly "weed" occasionally is applied pejoratively to species outside the plant kingdom, species that can survive in diverse environments and reproduce quickly; in this sense it has even been applied to humans.[2]

Answer:

Weed is a wild plant growing where it is not wanted and in competition with cultivated plants. The two common weeds are Amaranth and Taraxacum officinale. It is important to remove weeds from the fields because they rob soil moisture and nutrients from the crop and decrease harvest efficiencies. Weeds also compete with the crop for sunlight because they are competing to survive in a limited space. Weeds are actively removing nutrients from the soil to grow taller, stronger and healthier each day.
