Touch and look carefully at the bark of a tree. Do you see any animals, insects or plants on it?
On tree bark, various living organisms can be observed. Small insects like ants and beetles can be seen crawling, while spiders spin their webs on the bark surface.
Lichens appear as grey-green patches growing on the bark, and mosses grow in damp, shaded areas of the tree.
Small birds can also be observed resting on the bark. The bark provides shelter and habitat for many small creatures.
