Ants give plants 'intravenous' dose of nutrients
Targeted delivery of nutrient-rich waste from the insects provides plant leaves with the essential ingredients for their growth. Scientists have found out how ants help deliver plants an "intravenous" injection of nutrients. In a new article, researchers from Aarhus University reveal the symbiotic relationship between plant and insect. Ants' waste is rich in essential nutrients for plants. When they defecate on plant leaves they are leaving behind valuable fertiliser. Scientists have known for years that trees and smaller plants attract the ants by secreting a special sugar containing nectar from their leaves. Ants love eating this sugar and on their journey up the trunks and leaves of trees they'll snack on insects which could be harmful to the plant. In a laboratory setting the scientists built a miniature coffee plantation with several individual coffee trees. The central tree held a colony of weaver ants, and the base of each tree was pl...
